Abstract :
A novel traveling wave photodiode array (TWPDA) based on back-illuminated InGaAs-InP charge compensated modified uni-traveling carrier photodiodes is demonstrated. A two-element TWPDA with integrated termination resistor has a responsivity of 0.55 A/W and bandwidth of 17 GHz. The saturation photocurrent and the available electrical output power are 114 mA and + 13 dBm at - 3.5-V bias voltage, respectively.
