Abstract :
In conclusion, we have demonstrated a high-speed top illuminated resonant cavity enhanced (RCE) Schottky photodiode (PD) with semi-transparent Au contact. The 10 ps FWHM pulses measured on the scope are estimated to represent 4.3 ps FWHM impulse response, corresponding to a 3-dB bandwidth of 100 GHz. The optimized structure is expected to yield a bandwidth-efficiency product larger than 70 GHz
