  • Optically pumped laser with an integrated optical pump
    Patent number: 7826511
    Abstract: An apparatus and method for building an optically pumped laser integrated with an electrically driven pump laser is disclosed. The apparatus disclosed comprises an optically pumped laser containing an active layer and an optical pump laser containing an optical mode at least partially overlapping and propagating substantially parallel to optically pumped laser's active layer. The method discloses forming an optically pumped gain element containing an active layer, forming a pump laser containing an optical mode at least partially overlapping and propagating substantially parallel to optically pumped gain element's active layer.

  • Optically pumped stepped multi-well laser
    Patent number: 7266279
    Abstract: An apparatus and methods for an optically pumped laser that has a cascade of light-emitting interband transitions are disclosed. The apparatus disclosed contains multistep interband cascade regions able to generate a plurality of photons for a pump photon absorbed from an optical pump source. The methods disclosed teach how to produce a plurality of photons for a pump photon absorbed from an optical pump source.
