摘要: Optical taps are key elements for optical signal processing. The authors demonstrate the high-speed operation of an InGaAs p-i-n photodetector on InP waveguides. For a 300- mu m-long tap that samples 19% light propagating in 7- m-wide waveguide, response time is 50 ps at 1 V reverse bias. require simple epitaxial growth and can readily be integrated with electrooptic modulators other optoelectronic devices multigigahertz >
