| 英文摘要 | PURPOSE:To prevent the disconnection of wirings and the variation of a coupling degree due to a thermal stress of an optical fiber and to make the operation of a semiconductor laser module stable by controlling the temperature of the semiconductor laser module itself which is formed by hermetically sealing a semiconductor laser and a monitor diode and coupling it with the optical fiber, with an electronic cooling element. CONSTITUTION:A semiconductor laser 1, a spherical lens 2, and a monitor diode 3 of a semiconductor laser module are contained in a hermetical package 4 and a focusing type refractive index distribution cylindrical lens 5 is fixed to a through-hole of the package 4. An optical fiber 6 is arranged in a focusing position of the lens 5 by a supporting member 8. Such laser module is fixed on the side of a low temperature part 10 of an electronic cooling element 9 together with a temperature detecting element 11 and a high temperature part 12 is fixed to the inside wall of the package 14 comprising dual-in-line hermetical sealing terminals 13. The temperature of the laser module is controlled by the cooling element 9 and the generation of the disconnection of wirings and the variation of a coupling degree due to a thermal stress of the optical fiber 6 is prevented to make the operation of the laser module stable. |
