    摘要: PROBLEM TO BE SOLVED: To provide an optical semiconductor device using a CAN-type optical package which firmly connects a flexible substrate to the CAN-type optical package to maintain reliability as a product, while maintaining high-frequency signal reflection low at a connecting portion to obtain high-frequency characteristics.
    SOLUTION: High-frequency signal metal patterns are formed on the flexible substrate which is bent at almost right angles at ends of the signal metal patterns. The signal metal patterns are conductively fixed to signal lead pins attached to a stem to be virtually parallel with the signal lead pins. Some of the lead pins are inserted through-holes formed on the flexible substrate to be fixed conductively to some of the metal patterns on the flexible substrate.

    摘要: PROBLEM TO BE SOLVED: To provide a surface emitting semiconductor laser capable of reducing the resistance of an element, while avoiding increase in the parasitic capacitance, as well as, avoiding saturation of the t output, due to the drop in the heat dissipation performance.
    SOLUTION: A high resistance region 31b of semiconductor space layers 19, 21 extends along a side surface 19a of a resonator mesa 19 in the direction of a predetermined axis AX1, as well as, crossing a boundary B of the semiconductor spacer layers 19, 21. In a low-resistance region 31a, the conductive type of the semiconductor spacer layer 19 is different from the conductive type of the semiconductor spacer layer 21. The low-resistance region 31a is provided so as to extend along the side surface of a high-resistance region 31b and a side surface 29a of a resonator mesa 29, as well as, crossing the p-n junction 33 of the semiconductor spacer layers 19, 21. A second DBR 25 and a tunnel junction region 23 region located on a first region 13c. An active layer 17 and a first electrode 27 are located on the boundary line B, the first region 13c, and a second region 13d.
