This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of semiconductor nanostructures for all-optical signal processing is investigated. We first examine theoretically the utilization of quantum dots for wavelength conversion via four-wave mixing. Our results show that quantum dots with only a single bound state are more efficient than both quantum wells and quantum dots with a large number of excited states. We compare experimentally quantum dots and quantum wells with results which are consistent with our theoretical analysis. We measure the small-signal conversion of both single and multiple optical channels, and compare the results to cross-gain modulation in the same device. Our results show that four-wave mixing provides efficient, high-speed wavelength conversion in up to four, independent channels, and at speeds up to 40 GHz. Using a pulsed laser, we also examine the signal-to-noise ratio for the converted signal with our measurements showing an excellent signal to noise ratio and no patterning effect for a 25 ps pulse. To examine the theoretical limit of four-wave mixing for short pulses, we perform numerical calculations using the finite-difference beam propagation method in both a quantum dot and quantum well semiconductor optical amplifier. These calculations indicate that the quantum dot device performs better at the powers and speeds of relevance to telecommunications, but that the faster spectral hole relaxation rate of quantum wells allows for more efficient conversion of pulses less than 1 ps. We then examine how the cross-gain modulation response of the device can be increased and demonstrate that an additional pump field can create a cavity mode in the device which suppresses carrier oscillations and extends the XGM bandwidth from 1 GHz to greater than 25 GHz. Finally, we look at using a cavity mode for the purpose of slow- and fast-light and theoretically demonstrate that a fast- to slow-light transition occurs at the lasing threshold. These results compare well with previous measurements, and we present our own experimental investigations utilizing both a distributed-feedback laser and a ring laser. Utilizing a ring laser, we are able to achieve a delay bandwidth product of 10 for a 10 ps pulse in a single semiconductor device.

Book excerpt: Silicon photonics has evolved rapidly as a research topic with enormous application potential. The high refractive index contrast of silicon-on-insulator (SOI) shows great promise for submicron waveguide structures suited for integration on the chip scale in the near-infrared region. Ge- and GeSn-Si heterostructures with different elastic strain levels already provide expansion of the spectral range, high-speed operation, efficient modulation and switching of optical signals, and enhanced light emission and lasing. This book focuses on the integration of heterostructure devices with silicon photonics. The authors have attempted to merge a concise treatment of classical silicon photonics with a description of principles, prospects, challenges, and technical solution paths of adding silicon-based heterostructures. The book discusses the basics of heterostructure-based silicon photonics, system layouts, and key device components, keeping in mind the application background. Special focus is placed on SOI-based waveguide configurations and Ge- and GeSn-Si heterostructure devices for light detection, modulation, and light emission and lasing. The book also provides an overview of the technological and materials science challenges connected with integration on silicon. The first half of the book is mainly for readers who are interested in the topic because of its increasing importance in different fields, while the latter half covers different device structures for light emission, detection, modulation, extension of the wavelength beyond 1.6 μm, and lasing, as well as future challenges.

Download or read book Integrated Micro Ring Photonics written by Iraj Sadegh Amiri and published by CRC Press. This book was released on 2016-12-08 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications, where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits, since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems, multiple transmission, and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices, which will be able to be used with the mobile telephone. Therefore, the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication.

This book was released on 2013-09-05 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis breaks new ground in the physics of photonic circuits for quantum optical applications. The photonic circuits are based either on ridge waveguides or photonic crystals, with embedded quantum dots providing the single qubit, quantum optical emitters. The highlight of the thesis is the first demonstration of a spin-photon interface using an all-waveguide geometry, a vital component of a quantum optical circuit, based on deterministic single photon emission from a single quantum dot. The work makes a further important contribution to the field by demonstrating the effects and limitations that inevitable disorder places on photon propagation in photonic crystal waveguides, a further key component of quantum optical circuits. Overall the thesis offers a number of highly novel contributions to the field; those on chip circuits may prove to be the only means of scaling up the highly promising quantum-dot-based quantum information technology.

Download or read book Ultrabroad Bandwidth Slow Light in Semiconductor Nanostructures written by and published by . This book was released on 2008 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slow and fast light enables key functionality in various RF applications and all-optical networks. Semiconductor based schemes offer electrical control of velocity at very high bandwidths in an extremely compact device. Further they operate at room temperature and can be easily integrated into various optical systems. Ultra-fast non-linear processes in semiconductor optical amplifiers (SOAs) have been used to achieve tunable advance and delay at THz bandwidth. For a 700 fs pulse, we show electrically and optically controllable advance of 1.9 ps corresponding to an advance-bandwidth product (ABP) of 2.5. Further, by leveraging self-phase modulation in these devices we extend the performance to an ABP of 3.7. We develop comprehensive theory using density matrix approach to explain the experimental results. Our results show that an ultra-short pulse propagating through the SOA experiences non-linear index change due to spectral-hole burning and wave mixing between different spectral components. We derive analytical expressions for nonlinear index induced by these ultra-fast processes and numerically solve the propagation of an ultra-short pulse through the SOA. Our theoretical predictions agree very well with our experimental results. Finally, we show fast light for two ultra-short pulses separated by 7.2ps which demonstrates the feasibility of this scheme at high bit-rates.
