Book Description
A short pulse based optical link was demonstrated. It was shown that the short pulse link can remove up to half a bit of skew and jitter from the transmitter. Optoelectronic devices were fabricated and integrated to silicon chips in-house. A first generation wavelength division multiplexed optical link with short pulses was demonstrated and a second generation wavelength division multiplexed optical link system is described. Results are also shown for the testing of individual circuits and devices.

Book Description
In this study, small silicon photonics micro-resonator modulators and filters hold the promise for multi-terabit per-second interconnects at energy consumptions well below 1 pJ/bit. To date, no products exist and little known commercial development is occurring using this technology. Why? In this talk, we review the many challenges that remain to be overcome in bringing this technology from the research labs to the field where they can overcome important commercial, industrial, and national security limitations of existing photonic technologies.

Book Description
Internet information (which is doubling every six months) travels through optical fibers. Today, optical fibers are being installed where a single fiber has the ability to carry information as much as 200 times faster than was possible just five years ago. This revolutionary capability is being achieved with technology known as wavelength division multiplexing WDM). WDM technology relies on the fact that optical fibers can carry many wavelengths of light simultaneously without interaction between each wavelength. Thus, a single fiber can carry many separate wavelength signals or channels simultaneously. The communications industry is at the onset of new expansion of WDM technology necessary to meet the new demand for bandwidth. WDM Technologies: Optical Networks deals with the Networks facet of this field (present and future). - Allows engineers working in optical communications(from systems to components) to understand the principles and mechanics of each key component they deal with for optical system design - Provides an excellent resource for engineers and researchers engaged in all aspects of fiber optic communications, such as optoelectronics, equipment/system design, and manufacturing - Provides comprehensive coverage of key concepts in optical networks and their application in commercial systems

Book Description
Wafer-scale integration has long been the dream of system designers. Instead of chopping a wafer into a few hundred or a few thousand chips, one would just connect the circuits on the entire wafer. What an enormous capability wafer-scale integration would offer: all those millions of circuits connected by high-speed on-chip wires. Unfortunately, the best known optical systems can provide suitably ?ne resolution only over an area much smaller than a whole wafer. There is no known way to pattern a whole wafer with transistors and wires small enough for modern circuits. Statistical defects present a ?rmer barrier to wafer-scale integration. Flaws appear regularly in integrated circuits; the larger the circuit area, the more probable there is a ?aw. If such ?aws were the result only of dust one might reduce their numbers, but ?aws are also the inevitable result of small scale. Each feature on a modern integrated circuit is carved out by only a small number of photons in the lithographic process. Each transistor gets its electrical properties from only a small number of impurity atoms in its tiny area. Inevitably, the quantized nature of light and the atomic nature of matter produce statistical variations in both the number of photons de?ning each tiny shape and the number of atoms providing the electrical behavior of tiny transistors. No known way exists to eliminate such statistical variation, nor may any be possible.

Book Description
The serial optical data format has attracted attention for decades now, because of its promise to reduce the number of active components in a communication system. Indeed, historically increasing the serial bit rate by a factor of 4, reduced the cost per bit by 40%. Going beyond the available electronic bandwidth (roughly 100GHz today) can be obtained using optical time division multiplexing (OTDM), and symbol rates up to 1.28Tbaud per polarization have been demonstrated. As most optical signal processing devices operate on a per channel basis, it is advantageous to aggregate the data in a serial format, since this allows for optical signal processing of many bits in a single device. This chapter gives an overview of the state-of-the-art of OTDM systems to reach multi-Tbit/s serial data and means to handle these ultra-high bit rate signals using for instance nonlinear silicon waveguides for e.g. serial-to-parallel conversion.
