  • Patent number: 9020003
    Abstract: Blue laser diode (LD) structures are grown on a particular subset of semi-polar GaN substrate orientations that offer a distinct set of advantages relative to both (0001), non-polar oriented devices, and alternative semipolar-polar oriented devices operating in the blue regime are disclosed. In particular, the (30-3-1) and (30-31) gallium and nitrogen containing surface orientation and equivalent planes show narrower luminescence spectra than equivalent devices grown on the nonpolar {10-10} m-plane or semipolar planes tilted away from m-plane toward the c-plane between angles of about 0 degrees to about 7 or 8 degrees such as {60-6-1).

  • Patent number: 8848755
    Abstract: A system and method for providing laser diodes with broad spectrum is described. GaN-based laser diodes with broad or multi-peaked spectral output operating are obtained in various configurations by having a single laser diode device generating multiple-peak spectral outputs, operate in superluminescene mode, or by use of an RF source and/or a feedback signal. In some other embodiments, multi-peak outputs are achieved by having multiple laser devices output different lasers at different wavelengths.
