Abstract: Provided is a photo detector. The photo detector includes: an avalanche photodiode; a bias circuit supplying a bias voltage to one end of the avalanche photodiode; a detection circuit connected to the other end of the avalanche photodiode and detecting a photoelectric current occurring in the avalanche photodiode; and a coupling capacitor connected to the one end or the other end of the avalanche photodiode and supplying a coupling voltage to drive the avalanche photodiode in a Geiger mode.

Abstract: Provided is an avalanche photodetector with an integrated micro lens. The avalanche photodetector includes a light absorbing layer on a semiconductor substrate, an amplification layer on the light absorbing layer, a diffusion layer within the amplification layer, and the micro lens disposed corresponding to the diffusion layer. The micro lens includes a first refractive layer and a second refractive layer having a refractive index less than that of the first refractive layer.
