摘要： An optical transmitter with a heat dissipation structure is provided. The heat dissipation structure comprises a substrate and an optical transmitter unit. The substrate comprises a base body, a heat dissipation well disposed on the base body, and a thermal conductive block inserted into and fixed to the heat dissipation well. The thermal conductive block has on one side thereof a heat guiding plane. The optical transmitter unit comprises a heat dissipating substrate directly disposed on the heat guiding plane, and a laser diode directly disposed on the heat dissipating substrate. The laser diode features an active region whose height is lowered to shorten a heat conduction path wherein heat is transferred from the active region through the heat dissipating substrate to the heat guiding plane. The heat already transferred to the heat guiding plane is transferred horizontally by the thermal conductive block to the base body which encloses the heat dissipation well.

摘要： A method for increasing the bandwidth of an electroabsorption modulator (EAM) includes the following steps. First, a plurality of p-i-n active waveguides for the EAM are defined on a p-i-n optical waveguide forming an EAM having a shorter p-i-n active waveguide length. Then, the bandwidth of the EAM can be increased. Second, the high-impedance transmission lines are used in series to connect the EAM sections to reduce the microwave reflection and then increase the device bandwidth. Finally, the impedance-controlled transmission lines for the signal input and output can not only reduce the parasitic effects resulting from packaging, but also reduce the microwave reflection resulting from the impedance mismatch at the device input and load.

摘要： The invention provides a heat-dissipating semiconductor assembly, comprising: a heat-dissipating substrate, a metal solder layer, and an edge emitting laser diode. The heat-dissipating substrate has one side formed with a flat surface for mounting the edge emitting laser diode. The edge emitting laser diode is mounted on the metal solder layer, and by lowering the active area of the edge emitting laser diode, the active area of the edge emitting laser diode is drawn close to one side of the heat-dissipating substrate. The edge emitting laser diode has an optical output direction parallel to the flat surface of the heat-dissipating substrate, and the heat-dissipating substrate and/or the metal solder layer have a groove. The ridge of the edge emitting laser diode is aligned with an opening formed in the groove of the heat-dissipating substrate, thereby preventing the heat-dissipating substrate and metal solder layer from contacting the ridge of the edge emitting laser diode.

摘要： An optical communication module configured for enhancing optical coupling efficiency, which includes an optical butt joint receptacle and a light emitting body provided on one side of the optical butt joint receptacle. The optical butt joint receptacle has a receptacle body and a through hole provided in the receptacle body for a dual-core optical fiber to extend through. The receptacle body has a light-receiving side and an optical fiber insertion groove corresponding respectively to two ends of the through hole. The light emitting body includes a housing, a laser semiconductor provided in the housing, and an aperture provided in one side of the housing for aligning with the through hole so as that the laser beam emitted by the laser semiconductor is optically coupled to the dual-core optical fiber. The dual-core optical fiber has different core diameters and numerical apertures to enhance the coupling efficiency and reduce the coupling loss in between with the external optical fiber.
