Abstract
A high-speed, high-sensitivity photo-receiving device has a light-absorbing substrate, on which a pair of electrodes are provided. An insulative optical guide is located over an exposed surface portion of the substrate constituting an optical window. The optical guide is permeable to incident light, and the width of the optical guide does not exceed the wavelength of the incident light.
