LIGHT RECEIVING DEVICE, OPTICAL DEVICE AND METHOD OF MANUFACTURING LIGHT RECEIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light receiving device, or the like, which can obtain a high quality light reception signal, with high sensitivity, in the near-infrared through infrared region where the wavelength is about 0.7-3 μm.

SOLUTION: On the rear surface of an InP substrate 1, a microlens 21 is located in each region corresponding to a pixel. The microlens is formed of a resin material having a range of transmittance of 25% or less and 70% or more to the light having a wavelength of 0.7-3 μm.
