Highly Efficient, Ultra Low Dark Current Germanium Photodetectors Integrated on Submicron Silicon Waveguides

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate germanium photodetectors integrated on submicron silicon waveguides by low-temperature bonding and ion-cut. The devices show very low dark current of ~100 nA, fiber-accessed responsivity of 0.44 A/W, and quantum efficiency of > 90%.
