Abstract :
Saturation photocurrents of 56 mA has been achieved for velocity matched distributed photodetectors (VMDPs) with 49-GHz bandwidth. Theoretical calculation shows that saturation photocurrent greater than 100 mA can be achieved. In summary, we have reported the theoretical analysis and proposed the figure of merit (FOM) for high-power, high-speed photodetectors. The theoretical and experimental results show that the VMDP can achieve high saturation power and broad bandwidth
