Abstract:
A PD module comprising:a substrate;a first V-groove formed in the longitudinal direction on the substrate;a partition groove with a front wall and a rear wall formed in the lateral direction vertically to the first V-groove on the substrate for alignment and for facilitating an adhesive to pervade, the partition groove being deeper than the first V-groove;an optical fiber with a front end fixed in the first V-groove for guiding signal light, the front end of the fiber being in contact with the partition groove;a second V-groove with an end formed beyond the partition groove at an extension of the first V-groove on the substrate, the second V-groove being shallower than the first V-groove;a slanting reflection plane formed at the end of the second V-groove for reflecting the light from the fiber;a PD chip with a top and a bottom lying on the substrate above the second V-groove and the slanting reflection plane.
