Ultra-speed photodetector

Abstract

An ultra-speed photodetector includes a substrate, a light-absorbing layer, and a light-transmitting electrode layer. The light-absorbing layer located on the substrate. The electrode disposed on the light-absorbing layer and divided into a plurality of first electrodes and a plurality of second electrodes. A polarity of the first electrode is opposite to a polarity of the second electrode. The plurality of first electrodes arranged at intervals, and the second electrode located between the two adjacent first electrodes. A gap located between the first electrode and the second electrode that were adjacent to each other, and a portion of a surface of the light-absorbing layer exposed at the gap.
