Ultrawide-band/high-frequency photodetectors
WebVMDP offers many advantages for high frequency photodetectors with high saturation power. The distributed absorption is also desirable for increasing the damage threshold due to thermal runaway. Recently, we have experimentally demonstrated millimeter-wave generation at 95 GHz using a 1.55-pm VMDP. Web15 Jul 2015 · The frequency response is shown in Fig. 7, the obtained cut-off frequency is better, since the longest transit time of electrons serves to maintain the impulse response at a high level for a longer time period; the achieved cut-off frequency in this case is equal to 48.82 GHz.
