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： A standard multichannel optical fiber has a pitch 250 &mgr;m (P1), whereas mounting of optoelectronic device chips can require a pitch P2 larger than P1. The pitch of element fibers should be enlarged for coupling a multichannel ribbon fiber to a multichannel photodiode (PD) or laser diode (LD) module having photodiodes or laser diodes for M channels. The module includes a connector maintaining M fibers with tails extending backward and a bench having M V-grooves aligned at the larger pitch P2 for receiving the tails of the fibers. M light waveguides are aligned at the pitch P2 following the V-grooves. The module also includes M photodiodes or laser diodes following the light waveguides. A package includes the connector at a front part, the fiber tails at a width enlarging region for converging the pitch from P1 to P2, and the bench at a back part.
