OPTOELECTRONIC TECHNOLOGY FOR RECIRCULATING IMPLEMENTATION CROSSOVER INTERCONNECTION NETWORK

摘要

An optoelectronic recirculating implementation of the crossover interconnection network is presented in this paper. A flip-chip assembled CMOS/SEED (self-electro-optic-effect device) smart pixel array is used in this construction. The SEED array is composed of a number of detectors (receivers) and modulators (transmitters) while the CMOS devices make efficient logical processing. A light beam from a laser diode split by a binary phase grating (BPG) provides pumped light source for the modulators of the SEED array. After switched by the CMOS/SEED smart pixel array, the signal light beams become the output ones. They will be reused as inputs to the optoelectronic recirculating construction that utilizes a single stage setup to implement the whole crossover interconnection network. The advantages of this recirculating construction approach are its simplicity, flexibility and high speed.
