ABSTRACT:
An optical communication module, such as an optical transmitter used for optical communication incorporating a semiconductor laser (LD) and a monitoring photodiode (MPD), and an optical transceiver including a photodiode (PD), is efficiently and inexpensively provided. As means therefor, two substrates are used, that is, an expensive and high-accuracy first substrate is accommodated in an recess provided in a second substrate that is inexpensive and that needs less accuracy. An optical transmission system is mounted on the first substrate, and the MPD is mounted on the second substrate having an inclined surface provided on an opposite side of the recess in terms of the optical transmission direction. This eases production work and simultaneously allows the decreaseed use of expensive substrates.
