PROJECT TITLE: MSM-Photodetectors for high speed operation in multi-gigabit per second range
PROJECT DESCRIPTION: Plastic Optical Fiber (POF) and Polymer Clad Silica (PCS) fiber are actively developed for Gigabit applications. The demand for large area and high bandwidth photo-detectors is increasing. For POF/PCS systems transmitting data rate from 1Gbps to 3.2Gbps, GaAs Metal-Semiconductor-Metal photodetectors (MSM-PDs) are attractive solutions. We have fabricated MSM-PDs on 4 inch GaAs wafers. The large active area of 250m provides high alignment tolerances and high bandwidth with low cost packaging solutions. The technology is targeted for very short distance optical interconnects in the field of consumer electronics and datacom. The datacom applications include optical backplanes and inter-rack connections. The technology fills a gap in the previously available receiver technology. The new devices enable high speed operation in the multi-gigabit per second range using optical fibers of 200m diameter or larger.
