摘要： Optical gain of a nonpolar or semipolar Group-III nitride diode laser is controlled by orienting an axis of light propagation in relation to an optical polarization direction or crystallographic orientation of the diode laser. The axis of light propagation is substantially perpendicular to the mirror facets of the diode laser, and the optical polarization direction is determined by the crystallographic orientation of the diode laser. To maximize optical gain, the axis of light propagation is oriented substantially perpendicular to the optical polarization direction or crystallographic orientation.

摘要： A method for fabricating AlxGa1-xN-cladding-free nonpolar III-nitride based laser diodes or light emitting diodes. Due to the absence of polarization fields in the nonpolar crystal planes, these nonpolar devices have thick quantum wells that function as an optical waveguide to effectively confine the optical mode to the active region and eliminate the need for Al-containing waveguide cladding layers.

摘要： A III-nitride photovoltaic device structure and method for fabricating the III-nitride photovoltaic device that increases the light collection efficiency of the III-nitride photovoltaic device. The III-nitride photovoltaic device includes one or more III-nitride device layers, and the III-nitride photovoltaic device functions by collecting light that is incident on the back-side of the III-nitride device layers. The III-nitride device layers are grown on a substrate, wherein the III-nitride device layers are exposed when the substrate is removed and the exposed III-nitride device layers are then intentionally roughened to enhance their light collection efficiency. The collection of the incident light via the back-side of the device simplifies the fabrication of the multiple junctions in the device. The III-nitride photovoltaic device may include grid-like contacts, transparent or semi-transparent contacts, or reflective contacts.
