Available in PDF, EPUB and Kindle. Book excerpt: Photonic crystal devices are capable of controlling the flow of light in ultra compact scales. Silicon two dimensional (2D) nanostructures are well developed in the integrated circuit (IC) industry. Silicon is transparent to infrared light and has high refractive index which makes silicon an ideal material for photonic crystals in the infrared spectrum. Silicon 2D photonic crystals have attracted a lot of interest for showing feasibility of photonic integrated circuits. Typical photonic crystal devices are waveguides or cavities, which were developed as mostly passive devices. Various methods can be used to make photonic crystals tunable. In this work, silicon 2D tunable photonic crystal devices are studied using thermo-optic effect of silicon. In addition, this research presents one-step lithography to form micro and nano combined structures for the two-dimensional slab photonic crystals.

Download or read book Studies of Advanced Integrated Nano photonic Devices in Silicon written by Marcus Dahlem and published by . This book was released on 2011 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electronic-photonic integrated circuits (EPICs) are a promising technology for overcoming bandwidth and power-consumption bottlenecks of traditional integrated circuits. Silicon is a good candidate for building such devices, due to its high-index contrast and low propagation loss at telecom wavelengths. The current thesis presents recent advances in demonstrating discrete components built in silicon-on-insulator (SOI) platforms, around 1550 nm, that can be used as building blocks for future EPIC systems. The first part of this thesis investigates electro-optic modulators based on one-dimensional photonic crystal microcavities, with femtojoule switching energies, as well as on-chip optical interconnects using the super-collimation effect in two-dimensional photonic crystals, both in hole- and rod-based configurations. The second part focuses on microring-based structures, demonstrating wide thermal tunability and hitless operation of single-ring filters, as well as three more advanced categories of devices suitable for wavelength-division multiplexing (WDM) applications. These are twenty-channel second-order tunable filterbanks (both in dual- and counter-propagating configurations), reconfigurable optical add-drop multiplexers (ROADMs) with telecom-grade specifications, and a dynamical slow light cell for delay lines and optical memory elements. All the devices demonstrated in this thesis can be integrated on the same chip. The small device footprints and the use of the SOI platform are ideal for integration with a standard CMOS process, enabling the fabrication of novel electronic-photonic integrated circuits. These new EPIC systems may one day play an important role in the scaling of current computing systems and taking advantage of the WDM capability to increase operational bandwidth, while keeping the power consumption at low levels.

Download or read book Passive and Active Two dimensional Photonic Crystal Components written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic crystals are periodic dielectric structures having periodicity of the order of the wavelength. Consequently, they offer the ability to control the propagation of electromagnetic waves in a similar way as the periodic potential aspects the electron motion in a semiconductor crystal. By choosing the parameters of the photonic crystal, desired dispersion characteristics such as band gaps for light can be implemented, providing the possibility of creating miniaturized photonic components for integrated optical circuits. In this thesis, two-dimensional photonic crystal components with passive and active functionalities are designed, realized and investigated. The passive components, including photonic crystal cavities, waveguides and tight waveguide bends, are studied by means of far-field and near-field (heterodyne SNOM) measurement techniques addressing loss, quality factors and transmission efficiencies. The ability to tune or modulate the optical properties of photonic crystal devices increases their functionality and opens up new possibilities for applications. We present two ways of perturbing the optical environment near a photonic crystal cavity, enabling tuning and modulation of the in-plane transmission. Optical switching and wavelength tuning is obtained by means of induced thermal and plasma dispersion effects when focusing a laser onto a photonic crystal cavity structure, demonstrating the feasibility of high-speed optical integrated circuits based on silicon structures. On the other hand, tuning of the resonant wavelength and on-off switching of the transmission signal is achieved by probing the optical field confined within the resonant cavity by means of an atomic force microscope (AFM) tip, suggesting an integrated on-off switch or tunable filter. This thesis combines design, fabrication and measurement, thus bringing a better understanding of the fundamental properties of these types of photonic crystals, and helping to pave the way to practica.
