  • Patent number: 4069463
    Abstract: An array of closely spaced injection lasers is mounted upon a common substrate of grooved semiconductor or insulating material, with the active (hot) layers of the lasers as close as possible to the substrate. Individual grooves of relatively large cross-sectional area are formed in the portions of the substrate upon which the respective lasers are seated, each of these grooves underlying a respective one of the lasers, and each groove is filled with a material that has high thermal and electrical conductivity, thereby providing a massive beam lead which also serves to dissipate heat generated by the respective laser. The walls of the grooves are treated to provide electrical isolation between the beam leads, so that these leads can be used to establish individual switching connections to the active elements of the respective lasers.

  • Patent number: 4047124
    Abstract: An array of collimated wise aperture electrically pumped leaky corrugated AlGaAs optical waveguide lasers is formed on a single chip by etching a series of grooves oriented with respect to the crystalographic planes to isolate discrete lasers in the array and provide the requisite orientation of the internal reflecting surfaces to support the lasing action. The corrugation period is chosen such that the laser radiation exits from the array in a direction normal to the plane of waveguide.
