Membrane InGaAsP-bulk Photodetector Using Franz-Keldysh Effect for Wide Bandwidth and High Responsivity

We demonstrate an over-67-GHz-bandwidth O-band membrane photodetector (PD) with an InGaAsP-bulk core on a Si photonics platform. The membrane PD has a fiber-to-PD responsivity of 0.6 A/W. Clear eye opening is achieved for 100-Gbit/s non-return-to-zero signal.
