Abstract

PURPOSE:To use the titled device as the light source of a light wavelength division multiplex transmission system or a measuring instrument, etc., and to utilize laser beams effectively by mounting a multilayer film interference filter, which transmits oscillating wavelength beams and interrupts other wavelength beams, to a laser output window or output end surface of a semiconductor laser package. CONSTITUTION:A semiconductor laser chip 21 is fixed to a heat sink block 22, and the block 22 is mounted into the package 23. The multilayer film interference filter 41 is formed to the output window 40 outputting output beams 30 from the laser chip 21, and the filter 41 transmits the oscillating beams of the laser chip 21 and interrupts the beams of other wavelength. The laser chip 21 is used as the light source of the light wavelength division multiplex transmission system, and isolation among channels is increased. The laser chip 21 fixed to the heat sink block 22, the multilayer film interference filter 41 transmitting only the laser beams 30 is shaped to the cleavage face 61 of he active layer 60 of the laser chip 21, while the laser is employed as the light source of the measuring instrument, etc. requiring single beams.
