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

摘要

A light receiving device includes a microlens 21 located in each of regions corresponding to pixels, the microlens being disposed on a rear surface of an InP substrate 1. The microlens is formed by using a resin material having a range of a transmittance of light in the wavelength region between 0.7 and 3 µm of 25% or less, the transmittance being 70% or more.
