While optical communications are the standard solution for long haul communications, its adoption for short range (i.e, intra- and inter-chip interconnects and metro-area) transmission systems, where a considerable increase in data rates and a decrease in power consumption is to be gained, has been hampered mainly because the high cost associated to the fabrication of discrete optical components. The integration of photonic components in a single substrate, in what is known as silicon photonics, arises as a promising solution to overcome this limitation. Specifically, zero change CMOS silicon photonics, in which photonic components are fabricated in state of the art commercial microelectronic foundries without any change in the fabrication flow, therefore not modifying the transistor yield, enables the monolithic integration of electronics and photonics at a very low cost. Nevertheless, this comes at an expense in the control of the fabrication process and, as such, in the performance of the devices. It is of paramount importance, then, to carefully design, model and optimize these photonic components and test them experimentally. It is the object of this thesis to do so for one of the photonic components necessary for optical communications: modulators. To avoid high optical losses and achieve high optical confinement, the whispering gallery modes of silicon rings (with radii in the order of um) are exploited, and effective modulation is achieved by changing the carrier density in the silicon by means of pn junctions. In this thesis, high speed (25 Gbps) modulation at a working wavelength of 1550 nm is reported for the first time in a zero-change CMOS platform, and it is also demonstrated that this photonics platform can be readily used for low temperature (4 K) applications. A complete model of a silicon microring modulator that includes nonlinear effects (which can have an important detrimental effect in the device performance) is also derived, and from it power handling capabilities of these modulators are determined. By realizing high-speed an efficient optical modulators at the telecommunications wave- length, the potential of these CMOS photonics platform for addressing the future demands in the telecom and datacom systems by the fabrication of high scale electronic-photonic systems has been unveiled.

Download and read online ebook Broadband Circuits for Optical Fiber Communication write by Eduard Säckinger. This book was released on 2005-05-27. Broadband Circuits for Optical Fiber Communication available in PDF, EPUB and Kindle. 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.
