Paper Abstract

GaAs optoelectronic integrated circuits are having an increasing impact on the development of lightwave communication systems and very high sped digital and analog signal processors. However, cost-effective integration of complex electronic and optoelectronic circuits used in high speed networks or backplane interconnects still presents a significant technological challenge and substantial efforts are being devoted to the development of practical, low-loss integration processes. Photodetector/waveguide integration is a key aspect of the successful packaging of optoelectronic devices. In this work, metal-semiconductor- metal (MSM) photodetectors were integrated with polyimide ridge waveguides, and the processing parameters were varied for optimum performance. The absolute responsivities of the integrated MSM/polyimide waveguide structures were typically 0.5 A/W, and 3 dB bandwidths of 4-6 GHz were measured. Series of 1 X 2 and 1 X 4 photodetector arrays were interconnected, demonstrating a uniform division of the optical signal between the detectors. Results indicate that these arrays offer the potential to fabricate optoelectronic switches that can be used in a variety of high speed and broadband communication systems.
