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： The optical module comprises a ferrule, an optical fiber inserted into the ferrule, an optical communication functional unit for making the optical communication with the optical fiber, and a resin molded portion covering a part of the ferrule and the optical communication functional unit. The ferrule is provided with one or more concave grooves in a region exposed from the resin molded portion. Since this concave portion serves as a resin reservoir at the time of molding, the resin is prevented from adhering and covering on the outer surface of ferrule exposing from the resin molded portion.

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.

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.
