  • Monolithically integrated semiconductor structure and method of fabricating such structure
    Patent number: 5355386
    Abstract: A heterostructure device includes a ridge-waveguide laser monolithically integrated with a ridge-waveguide rear facet monitor (RFM). An integral V-groove etched directly into the device substrate enables passive alignment of an optical fiber to the active region of the laser. The laser and RFM facets were formed using an in-situ multistep reactive ion etch process.
