This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: To date, the realization of chip-scale optical interconnects has been inhibited by the lack of a device technology that can provide optical functionality at a scale commensurate with integrated circuits. To overcome this limitation, I propose the realization of an "optical superhighway" as an alternative interconnect paradigm for next-generation integrated circuits using semiconductor-based photonic-crystal (PhC) devices. PhCs have the potential to be the elementary building blocks of the next generation of opto-electronic devices and integrated circuits. This potential has invigorated global research interest in hybrid optical-electrical interconnects at the chip scale. In this thesis, I will present the development of such Nano-Photonic Crystal (PhC) interconnects using conventional CMOS fabrication technology, thereby enabling photonic functionality on the VLSI scale. Accordingly, I will discuss the fabrication of high fill-factor planar PhC devices on silicon-on-insulator substrates, using both capacitively coupled and inductively coupled plasma etching. Functional, sub-100-nm, high-aspect-ratio PhC devices will be presented, along with the technical challenges encountered in their realization. Also, a robust etch-process toolbox has been developed that, in addition to realizing chip-scale optical interconnects, also paves the way for applications in other technology niches like MEMS, terahertz devices, nanophotonics and microfluidics, to be realized in a single silicon platform, thus enabling systems-on-a-chip. In-plane optical routing in ultra-thin silicon-on-sapphire is also explored as part of this investigation. In addition, I will discuss the development of a sub-surface silicon optical bus (S3B), a buried silicon optical interconnect technology. The approach relies on engineering the dispersion properties of three-dimensional (3D) photonic crystals embedded in silicon to control light propagation. In particular, a novel method of fabricating buried 3D photonic-crystal structures using conventional planar silicon micromachining will be presented. This method utilizes a single planar etch mask and time-multiplexed etch process along with sidewall oxidation to create an array of spherical voids with three-dimensional symmetry. Preliminary results will be presented to support the feasibility of realizing chip-scale optical interconnects using the proposed approach. The results of this research will not only help realize a new generation of optical integrated circuits, but also provide a solution to the global interconnect delay anticipated in next-generation of high-end integrated circuits. These PhC devices could very well provide the building blocks for the integrated circuits of the future.

Available in PDF, EPUB and Kindle. Book excerpt: Photonic crystals (PhCs) are envisioned as the semiconductors for photonics technology and are believed to be the key materials/platforms for photonic integration. The development of PhCs has enabled groundbreaking approaches to mold the flow of electromagnetic waves with frequency spanning from RF regime to optical domain. The applications of PhCs fall into two categories: bandgap-engineering and dispersion-engineering. Research presented in this dissertation focuses on the novel dispersion properties and some of the first-ever applications of dispersion-engineered PhCs. By engineering the dispersion of a 2D PhC, a flat cylindrical lens was designed and fabricated, through which 2D negative refraction and 2D subwavelength imaging were experimentally demonstrated in both amplitude and phase. The results achieved in the 2D structure provided the principal insights into negative refraction. Further effort was then focused on materials exhibiting full 3D negative refraction due to their practical applications and theoretical interests in them. Full 3D negative refraction and 3D subwavelength imaging were then experimentally achieved by engineering the dispersion of a 3D body-centered cubic PhC. Negative refraction flat lenses provided super-resolution and curvature-free imaging, which can find potential applications in improving the performance of optical tweezers and allows the construction of an optical tweezers array with a single negative refraction flat lens. To this end, microwave electromagnetic trapping and manipulation of neutral particles were experimentally realized using the full 3D negative-refraction flat lens. In addition to negative refraction, self-collimation of electromagnetic waves in 2D and 3D PhCs was also theoretically investigated and experimentally demonstrated. Self-collimation of electromagnetic waves was numerically simulated and experimentally observed even in low-index-contrast 2D PhCs. Furthermore, self-collimation was also achieved in a 3D PhC by engineering the dispersion property of a simple cubic PhC. Self-collimation allows for creating "non-diffractive materials", in which light can propagate without divergence while no specific route is introduced. The potential applications of this novel effect include high-density optical interconnection with low optical-channel crosstalk. By combining a novel fiber-to-chip interconnect technique which we developed, a framework is provided to realize chip-to-chip and on-chip optical interconnects. The uniqueness of this research is that dispersion properties of both 2D and 3D PhCs are explored, and experimental device characterization is demonstrated in both amplitude and phase. Although a large part of the research was carried out in the millimeter-wave regime, the demonstration of negative refraction imaging at near infrared frequencies also verified that all the dispersion-engineered PhC devices can potentially be scaled to nanometer dimensions for applications in the optical regime.

Download or read book Photonic Crystals written by Qihuang Gong and published by CRC Press. This book was released on 2014-02-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a broad overview of photonic crystals and, as the title suggests, covers their principles and applications. It is written from a physics point of view with an emphasis on materials science. Equations are well explained and often completely avoided to increase the readability of the book. The book is divided into eight chapters, starting with a brief introduction. The second chapter deals with different dimensionalities of the photonic crystals and their properties. The third chapter is very interestingly written and provides a survey of the various synthesis methods used for production of photonic crystals, including chemical routes, lithography, and self-assembly of colloidal photonic crystals. Chapters 4–8 constitute the bulk of the book and provide examples of applications of these photonic crystals. Chapter 4 offers a good explanation of optical switching. Bandgap and defect mode switching are also brought into focus along with many other mechanisms—14 different switching mechanisms in all, including thermal, electro, and magneto switching. Frequency tuning of photonic crystal filters with special attention to nanosize photonic crystals is illustrated, providing a direct perspective on applications of these materials in integrated photonic circuits. The transition from chapter 5 to 6 dealing with photonic crystal lasers is smooth, especially after a clear description of frequency tuning. Here, one- to three-dimensional photonic lasers are explained along with laser oscillations produced by a variety of microcavity methods. Metallodielectric and liquid-crystal photonic lasers are equally well illustrated. Chapter 7 introduces logic devices based on photonic crystals. This chapter clearly explains, with the help of simple illustrations, how to obtain AND, OR, and XOR logic gates. Chapter 8 concludes the book by presenting possible applications, including gas, chemical, fluid, and cell sensing; their workings are very well described from a fundamental point of view. The diagrams and illustrations are appropriate and eye catching. There are ample references; thus readers are able to find more detailed information to satisfy their curiosity if the book does not suffice. Even though the introduction provides basics of these photonic crystals, I do get the impression that the bigger picture is missing. A nonexpert may not understand the direct application of such materials right from the beginning of the book. A flowchart or a diagram of these photonic crystals, illustrating applications in daily life at the beginning of the book, could attract a broader readership. In this regard, I believe that this book is most adapted to physicists with a materials science background or vice versa. However, one should take into consideration that the principles of photonic crystals cannot be explained without physics, and therefore the quality of this book remains intact and could very well serve as a textbook for future physicists.

Book excerpt: The search for a photonic crystal to confine optical waves in all three dimensions (3D) has proven to be a formidable task. It evolves from an early theoretical suggestion [1,2], a brief skepticism [3-5] and triumph in developing the mm-wave [6-8] and infrared 3D photonic crystals [9]. Yet, the challenge remains, as the ultimate goal for optoelectronic applications is to realize a 3D crystal at X=1.5 pm communication wavelengths. Operating at visible and near infrared wavelengths, X=1-2 pm, a photonic crystal may enhance the spontaneous emission rate [1, 10] and give rise to a semiconductor lasers with a zero lasing threshold[11, 12]. Another important application is optically switching, routing and interconnecting light [13,14] with an ultrafast transmission speed of terabits per second. A photonic crystal may also serve as a platform for integrating an all-optical circuitry with multiple photonic components, such as waveguides and switches, built on one chip [15]. In this Letter, we report on the successful fabrication of a working 3D crystal operating at optical L The minimum feature size of the 3D structure is 180 nanometers. The 3D crystal is free from defects over the entire 6-inch silicon wafer and has an absolute photonic band gap centered at A.-1.6 pm. Our data provides the first conclusive evidence for the existence of a full 3D photonic band gap in optical A. This development will pave the way to tinier, cheaper, more effective waveguides, optical switches and lasers.

Available in PDF, EPUB and Kindle. Book excerpt: As a reason of information explosion, electronic communication networks are not sufficient for high bit rate data transmission. This problem has been solved by optical networks which caused the birth of a new area of technology, photonics. In photonic circuits photons play the dominant role and they transfer the optical data. With the growth of the photonics technology, a new area started to grow as photonic crystals which now play an important role in designing and manufacturing compact photonic devices. Photonic crystals are structures with alternative dielectric constant in one, two or three dimensions which are called one, two or three dimensional photonic crystals. By using the properties of photonic band gap, many interesting phenomena such as slow light generation, dispersion engineering in a compact and low size device can be achieved.
