  • Monolithic semiconductor laser and optical amplifier
    Patent number: 4744089
    Abstract: An integrated semiconductor source of high-power, single spatial mode, narrow spectral mode modulated radiation. A frequency selective feedback laser diode is disposed on the same semiconductor crystal with a power amplifier having a diverging active area which causes emitted light to be distributed over a large exit facet area.
    Type: Grant
    Filed: May 19, 1986
    Date of Patent: May 10, 1988
    Assignee: The Perkin-Elmer Corporation
    Inventors: Andrew H. Montroll, Steven H. Macomber
  • Semiconductor laser and optical amplifier
    Patent number: 4713821
    Abstract: A semiconductor source of high power, spatially and temporally coherent light including means to prevent damage to the output face. A laser diode is disposed in optical contact with a power amplifier having a diverging active area which causes emitted light to be distributed over a large facet area.
