This book was released on 2010 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information processing requires interconnects to carry information from one place to another. Optical interconnects between electronics systems have attracted significant attention and development for a number of years because optical links have demonstrated potential advantages for high-speed, low-power, and interference immunity. With increasing system speed and greater bandwidth requirements, the distance over which optical communication is useful has continually decreased to chip-to-chip and on-chip levels. Monolithic integration of photonics and electronics will significantly reduce the cost of optical components and further combine the functionalities of chips on the same or different boards or systems. Modulators are one of the fundamental building blocks for optical interconnects. Previous work demonstrated modulators based upon the quantum confined Stark effect (QCSE) in SiGe p-i-n devices with strained Ge/SiGe multi-quantum-well (MQW) structures in the i region. While the previous work demonstrated the effect, it did not examine the high-speed aspects of the device, which is the focus of this dissertation. High-speed modulation and low driving voltage are the keys for the device's practical use. At lower optical intensity operation, the ultimate limitation in speed will be the RC time constant of the device itself. At high optical intensity, the large number of photo generated carriers in the MQW region will limit the performance of the device through photo carrier related voltage drop and exciton saturation. In previous work, the devices consist of MQWs configured as p-i-n diodes. The electric field induced absorption change by QCSE modulates the optical transmission of the device. The focus of this thesis is the optimization of MQW material deposition, minimization of the parasitic capacitance of the probe pads for high speed, low voltage and high contrast ratio operation. The design, fabrication and high-speed characterization of devices of different sizes, with different bias voltages are presented. The device fabrication is based on processes for standard silicon electronics and is suitable for mass-production. This research will enable efficient transceivers to be monolithically integrated with silicon chips for high-speed optical interconnects. We demonstrated a modulator, with an eye diagram of 3.125GHz, a small driving voltage of 2.5V and an f3dB bandwidth greater than 30GHz. Carrier dynamics under ultra-fast laser excitation and high-speed photocurrent response are also investigated.

Download or read book Broadband Circuits for Optical Fiber Communication written by Eduard Säckinger and published by John Wiley & Sons. This book was released on 2005-05-27 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: An expert guide to the new and emerging field of broadband circuits for optical fiber communication This exciting publication makes it easy for readers to enter into and deepen their knowledge of the new and emerging field of broadband circuits for optical fiber communication. The author's selection and organization of material have been developed, tested, and refined from his many industry courses and seminars. Five types of broadband circuits are discussed in detail: * Transimpedance amplifiers * Limiting amplifiers * Automatic gain control (AGC) amplifiers * Lasers drivers * Modulator drivers Essential background on optical fiber, photodetectors, lasers, modulators, and receiver theory is presented to help readers understand the system environment in which these broadband circuits operate. For each circuit type, the main specifications and their impact on system performance are explained and illustrated with numerical values. Next, the circuit concepts are discussed and illustrated with practical implementations. A broad range of circuits in MESFET, HFET, BJT, HBT, BiCMOS, and CMOS technologies is covered. Emphasis is on circuits for digital, continuous-mode transmission in the 2.5 to 40 Gb/s range, typically used in SONET, SDH, and Gigabit Ethernet applications. Burst-mode circuits for passive optical networks (PON) and analog circuits for hybrid fiber-coax (HFC) cable-TV applications also are discussed. Learning aids are provided throughout the text to help readers grasp and apply difficult concepts and techniques, including: * Chapter summaries that highlight the key points * Problem-and-answer sections to help readers apply their new knowledge * Research directions that point to exciting new technological breakthroughs on the horizon * Product examples that show the performance of actual broadband circuits * Appendices that cover eye diagrams, differential circuits, S parameters, transistors, and technologies * A bibliography that leads readers to more complete and in-depth treatment of specialized topics This is a superior learning tool for upper-level undergraduates and graduate-level students in circuit design and optical fiber communication. Unlike other texts that concentrate on analog circuits in general or mostly on optics, this text provides balanced coverage of electronic, optic, and system issues. Professionals in the fiber optic industry will find it an excellent reference, incorporating the latest technology and discoveries in the industry.
