Abstract :
We report a monolithic chip incorporating an eight channel p-i-n/HBT photoreceiver array designed for multi-channel WDM applications. The p-i-n photodetectors are edge illuminated and centered at the right distance for mating with either ribbon fiber connectors or waveguide demultiplexers. Each channel operates at 2.5 Gb/s with an electrical cross talk of -20 dB between adjacent channels. The average sensitivity of each receiver in the array was measured to be (-20±1) dBm for a bit error rate of 10-9 at a wavelength of 1.5 μm
