Parallel feed travelling wave distributed pin photodetectors with integrated MMI couplers
17 January 2002
The fabrication and performance of a parallel feed travelling wave photodetector with pin diodes operating at 1550 nm is presented. A parallel optical teed tiling an integrated multimode interference (MMI) power splitter helps increase the maximum linear photocurrent through a more uniform distribution of photocurrent. The maximum DC linear current measured is 52.2 mA. Maximum linear RF power at 10 GHz was 9 dBm.
