High Performance Seed Based Optical Computing.
Abstract
An optoelectronic switching fabric demonstration is presented that makes use of a single optoelectronic switching chip. The chip consists of the integration of thousands of multiple quantum well optical (MQW) modulators and detectors with silicon complementary metal oxide semiconductor (CMOS) very large scale integrated (VLSI) circuits. An optical system images an array of signals from a two-dimensional fiber optic bundle onto the chip and images the signal outputs from the chip onto the fiber array. Diffractive optical elements are used to reduce the numerical aperture of the light coming from the fibers and to provide optical fan-out of both the signal beams and read beams incident on the detectors and modulators respectively. A novel architecture was developed that enabled this demonstration to be part of a distribution fabric for an asynchronous transfer mode (ATM) switching network with an appropriate out-of-band controller.
