Abstract
A light receiving module having a built-in wavelength-tunable wavelength-selective filter that can selectively receive light with a specific wavelength from laser light with various wavelengths emitted from an optical fiber and tune the specific wavelength. In the light receiving module including a light receiving element having a built-in wavelength-tunable wavelength-selective filter that receives laser light from an optical fiber according to the present invention, a flat plate-shaped window () transmitting laser light from an optical fiber () is formed in the light receiving element (), a wavelength-tunable wavelength-selective filter for separating wavelengths of laser light traveling as parallel light is disposed in the light receiving element (), and a lens () converting laser light from the optical fiber () into parallel light is disposed between the optical fiber () and the light receiving element ().
