    摘要： An optical communication module having a roughened bottom of a silicon bench for suppressing optical crosstalk. The roughened bottom prevents stray laser beams from reflecting toward a photodiode. The roughened bottom is further covered with a photoabsorbent resin, pigment or adhesive for absorbing the stray laser beams at a bottom. A cladding of a lightwaveguide are narrowed and are painted with a photoabsorbent resin, pigment or adhesive for absorbing horizontally stray beams propagating in the cladding.

    摘要： An optical communications module in which electrical crosstalk is reduced. The term “optical communications module” represents a surface-mounting-type optical tranceiver, transmitter, or receiver module. The optical communications module has a following structure. (a) An Si substrate carries at least one signal-transmitting section comprising an LD, at least one signal-receiving section comprising a PD, or both together with other components. (b) An insulating substrate is bonded to the back face of the Si substrate. (c) A separating groove separates the Si substrate along the or each boundary line between the sections in order to prevent an AC current flowing through the Si substrate. To attain this object, the separating groove is provided from the top surface of the Si substrate to some midpoint of the insulating substrate. This structure reduces the electrical crosstalk between the signal-transmitting section and the signal-receiving section, between the signal-transmitting sections, and between the signal-receiving sections.

    摘要： 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.
