Hybrid Plasmonic Ring-Resonator Uni-Traveling Carrier Pin-Photodetector on InGaAsP/InP Layer Stack

In this article, for the first time, a hybrid plasmonic (HP) ring resonator uni-traveling carrier pin-photodetector was numerically presented that offers a high responsivity of 0.68 A/W, a high bandwidth of over 125 GHz, and low footprint. This device has the capability of monolithic integration with HP-passive devices on the InP platform at an optical communication wavelength of 1550 nm.
