Ly. Lin et al., VELOCITY-MATCHED DISTRIBUTED PHOTODETECTORS WITH HIGH-SATURATION POWER AND LARGE BANDWIDTH, IEEE photonics technology letters, 8(10), 1996, pp. 1376-1378
A high-power, high-bandwidth photodetector is experimentally demonstra
ted using a novel velocity-matched distributed photodetector (VMDP), T
he distributed photodetector structure can achieve large absorption vo
lume and high-saturation power while maintaining the high-speed perfor
mance of the fast photodiodes, The VMDP with 56 mA saturation photocur
rent and an instrument-limited 3-dB bandwidth of 49 GHz is achieved, T
he results show that VMDP is ideal for high-performance microwave fibe
r-optic links and high-power optical-microwave applications.
