Abstract

We propose a photodetector (PD) based on the internal photoemission effect over a Schottky barrier on a CMOS-compatible Si microring resonator for 1.55 μm. To analyze the device, we model the microring waveguide partially covered by a metal/silicide nanolayer, using the Z-transform method. The proposed structure benefits from the resonant-cavity-enhanced (RCE) waveguide PDs enjoying high efficiency and wavelength selectivity. Simulations show that the maximum value of the bandwidth-efficiency product for the proposed structure is in the order of 10 GHz, which is much higher than those reported for other RCE-based PDs.
