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 transmission module is constructed in a configuration wherein a semiconductor laser is mounted on a stem-side emitter loading portion of a pole provided on a stem and wherein light emitted forward from the semiconductor laser is outputted through a condenser lens and others. A monitor photodiode is mounted on a receiver loading portion of the pole on the forward side of the semiconductor laser and the photodiode detects part of the light emitted forward from the semiconductor laser, to monitor the operating condition of the semiconductor laser. This configuration achieves decrease in the length of a lead pin and thus restrains deterioration of the waveform of the drive current to the semiconductor laser.

摘要： An optical receiver comprises (a) an optical fiber, (b) a rear-illuminated type PD for receiving incoming light emerging from the optical fiber, (c) a submount supporting the PD, (d) a coaxial type package housing the submount, and (e) a preamplifier IC for amplifying electric signals from the PD. In particular, the submount is provided with a reflecting face for reflecting the incoming light so that the light can enter the PD. The submount may be provided with an optical path-forming groove having at least one reflecting face for introducing and reflecting the incoming light so that the light can enter the light-receiving portion of the PD mounted on the submount. This structure enables the production of an optical receiver most suitable for high-speed response and excellent in productivity. A method of producing the optical receiver is also offered.

Thus, the optical communications module can exhibit excellent performance.
