Abstract

High power requirements of the traveling wave photodetector array increase the structure complexity and reduce the response speed.In order to solve this problem

a kind of improved Traveling-Wave Detector Arrays（TWDA）structure based on diode groups is proposed.The power synthesis

frequency response and return loss of traveling-wave photodiode arrays are compared and analyzed.Under the condition of same amount of diode

the improved TWDA structure uses less inductive element with constant output power and the working bandwidth

and much smaller return loss.The research results show that the improved structure can streamline the structure of the original circuit while improving its response speed and circuit matching performance with better satisfying the requirements of power.
