Download or read book High Performance Photodetectors for Multimode Optical Data Links written by Wojciech Piotr Giziewicz and published by . This book was released on 2006 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Silicon detectors of various geometries were fabricated, with measured bandwidths at 5 V reverse bias up to 2 GHz for 200 ym diameter devices and 4 GHz for 50 and 100 ym diameter devices. The latter is the highest bandwidth reported for a silicon detector fabricated in a CMOS-compatible process and biased at a practically accessible voltage. Device performance was confirmed by simulation, and a novel structure is proposed featuring a buried junction on SOI determined by simulation to have twice as high a responsivity-bandwidth product as the best reported devices fabricated on high resistivity SOI. The silicon device structure was modified for epitaxial germanium wafers, and devices were fabricated. The germanium devices were simulated to determine the appropriate technology scaling direction and maximum device dimensions for desired performance specifications.

Download or read book Optical Communication over Plastic Optical Fibers written by Mohamed Atef and published by Springer. This book was released on 2012-10-31 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents high-performance data transmission over plastic optical fibers (POF) using integrated optical receivers having good properties with multilevel modulation, i.e. a higher sensitivity and higher data rate transmission over a longer plastic optical fiber length. Integrated optical receivers and transmitters with high linearity are introduced for multilevel communication. For binary high-data rate transmission over plastic optical fibers, an innovative receiver containing an equalizer is described leading also to a high performance of a plastic optical fiber link. The cheap standard PMMA SI-POF (step-index plastic optical fiber) has the lowest bandwidth and the highest attenuation among multimode fibers. This small bandwidth limits the maximum data rate which can be transmitted through plastic optical fibers. To overcome the problem of the plastic optical fibers high transmission loss, very sensitive receivers must be used to increase the transmitted length over POF. The plastic optical fiber limited bandwidth problem can be decreased by using multilevel signaling like multilevel pulse amplitude modulation or by using an equalizer for binary data transmission.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic increases in processing power have rapidly scaled on-chip aggregate bandwidths into the Tb/s range. This necessitates a corresponding increase in the amount of data communicated between chips, so as not to limit overall system performance. To meet the increasing demand for interchip communication bandwidth, researchers are investigating the use of high-speed optical interconnect architectures. Unlike their electrical counterparts, optical interconnects offer high bandwidth and negligible frequency-dependent loss, making possible per-channel data rates of more than 10 Gb/s. High-Speed Photonics Interconnects explores some of the groundbreaking technologies and applications that are based on photonics interconnects. From the Evolution of High-Speed I/O Circuits to the Latest in Photonics Interconnects Packaging and Lasers Featuring contributions by experts from academia and industry, the book brings together in one volume cutting-edge research on various aspects of high-speed photonics interconnects. Contributors delve into a wide range of technologies, from the evolution of high-speed input/output (I/O) circuits to recent trends in photonics interconnects packaging. The book discusses the challenges associated with scaling I/O data rates and current design techniques. It also describes the major high-speed components, channel properties, and performance metrics. The book exposes readers to a myriad of applications enabled by photonics interconnects technology. Learn about Optical Interconnect Technologies Suitable for High-Density Integration with CMOS Chips This richly illustrated work details how optical interchip communication links have the potential to fully leverage increased data rates provided through complementary metal-oxide semiconductor (CMOS) technology scaling at suitable power-efficiency levels. Keeping the mathematics to a minimum, it gives engineers, researchers, graduate students, and entrepreneurs a comprehensive overview of the dynamic landscape of high-speed photonics interconnects.

Book excerpt: Every bit of information that circulates the internet across the globe is a pulse of light, that at some point will need to be converted to an electric signal in order to be processed by the electronic circuitry in our data centers, computers, and cell phones. Photodetectors (PD's) perform this conversion with ultra high speed and efficiency, in addition to being ubiquitously present in many other devices ranging from the mundane TV remote controls, to ultra high resolution instrumentation used in Laser Interferometer Gravitational Wave Observatory (LIGO) that reach the edge of the universe and measure gravitational waves. The second edition of "Photodetectors" fully updates the popular first edition with updated information covering the state-of-the-art in modern photodetectors. The 2nd edition starts with basic metrology of photodetectors and common figures-of-merit to compare various devices. It follows with chapters that discuss single-photon detection with Avalanche Photodiodes; organic photodetectors that can be inkjet printed; and silicon-germanium PDs popular in burgeoning field of Silicon Photonics. Internationally recognized experts contribute chapters on one-dimensional, nanowire, PDs as well as high speed zero-dimensional, quantum dot, versions that increase the spectral span as well as speed and sensitivity of PDs and can be produced on various substrates. Solar-blind PDs that operate in harsh environments such as deep space, or rocket engines, are reviewed and new devices in GaN technology . Novel Plasmonic PDs, as well as devices which employ micro-plasma of confined charge in order to make devices that overcome speed limitation of transfer of electronic charge, are covered in other chapters. Using different, novel technologies, CMOS compatible devices are described in two chapters, and ultra high speed PDs that use low-temperature-grown GaAs (LT-GaAs) to detect fast THz signals are reviewed in another chapter. Photodetectors used in application areas of Silicon-Photonics and Microwave-Photonics are reviewed in final chapters of this book. All chapters are of a review nature, providing a perspective of the field before concentrating on particular advancements. As such, the book should appeal to a wide audience that ranges from those with general interest in the topic, to practitioners, graduate students and experts who are interested in the state-of-the-art in photodetection. - Addresses various photodetector devices from ultra high speed to ultra high sensitivity, capable of operation in harsh environments - Considers a range of applications for this important technology, including silicon photonics and photonic integrated circuits - Includes discussions of detectors based on reduced dimensional systems such as quantum wells, nanowires, and quantum dots, as well as travelling wave, and plasmonic detectors

This book was released on 1987 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of long wavelength (1.3 to 1.65 micrometer) Schottky barrier photodetectors in InGaAs/InP. Two material overlays were investigated. These are the Au/P+-n- 0.43A/W and a quantum efficiency of 40.5% at 1.3 micron m without an antireflection coating. The impulse response gave a rise time of 85 ps and a FWHM of 490 ps. The RC time constant measured was 34.7 ps which corresponds to a cutoff frequency of 28.8 GHz. The n+-InP Schottky barrier requires more work to obtain good reproducibility of the barrier height enhancement technique employed. The work performed indicates that long wavelength, high frequency response, Schottky barrier for use as fiber optic compatible detectors are viable. Processing techniques are described along with supportive device modeling and experimental data on the initial devices. Keywords include: Detectors, Optical, Fiber optics, Long wavelength, and Schottky barrier.
