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 heat dissipation structure of a horizontal optical-communication sub-assembly is provided, which includes a T-shaped header, a circuit board and a heat-dissipating support insert. The T-shaped header includes a base and a tongue. The tongue is disposed on one side of the base and is perpendicular to the base. The base includes a first through hole and a second through hole. The first through hole is above the tongue and the second through hole is below the tongue and opposite to the first through hole. One end of the circuit board penetrates through the first through hole and disposed on the tongue. The heat-dissipating support insert includes a supporting block and an extension portion.

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.
