Abstract:
A light receiving module comprising:an optical fiber-supporting member, provided with:one or more optical fiber-fixing grooves formed on a surface of a first substrate for fixing one or more parts of one or more optical fibers near their output ends, andone or more light direction-changing means formed at side ends of said optical fiber-fixing grooves and directing one or more lights emitted from one or more light-emitting surfaces of said one or more optical fibers, anda photodiode-forming member, which is provided with:one or more photodiodes having one or more light receiving surfaces and arrayed on a second substrate at a certain interval, said one or more light receiving surfaces being set close to said one or more light-emitting surfaces of said one or more optical fibers, andat least two raised portions arranged on a portion of the second substrate, with a gap having a bottom portion provided between each of two raised portions, said raised portions spaced apart from said photodiode along a longitudinal direction and adapted for pressing said one or more optical fibers against said optical fiber-fixing grooves without masking said one or more light-emitting surfaces, said bottom portion of said gap being flush with a surface of said photodiode-forming member,wherein, an attitude of said photodiode-forming member relative to said optical fiber-supporting member is so adjusted that said one or more lights are precisely incident on said corresponding one or more light receiving surfaces, and both said photodiode-forming and optical fiber-supporting members are stuck together keeping said relative attitude unchanged.
