S. Chandrasekhar et al., 8-CHANNEL P-I-N HBT MONOLITHIC RECEIVER ARRAY AT 2.5 GB S PER CHANNELFOR WDM APPLICATIONS/, IEEE photonics technology letters, 6(10), 1994, pp. 1216-1218
We report a monolithic chip incorporating an eight channel p-i-n/HBT p
hotoreceiver array designed for multichannel WDM applications. The p-i
-n photodetectors are edge illuminated and centered at a 250mum pitch
for mating with either ribbon fiber connectors or waveguide demultiple
xers. Each channel operates at 2.5 Gb/s with an electrical crosstalk o
f -20 dB between adjacent channels. The average sensitivity of each re
ceiver in the array was measured to be (-20+/-1) dBm for a bit error r
ate of 10(-9) at a wavelength of 1.5mum.
