Abstract:
1. A laser diode device on a gallium and nitrogen semipolar substrate, the laser diode device comprising: a first waveguide section provided on the semipolar substrate extending in a projection of a c-direction, the first waveguide section having a first gain and loss characteristic and having a first end and a second end; a second waveguide section provided on the semipolar substrate and is substantially perpendicular to the first waveguide section and extending in an m-direction, the second waveguide section having a second gain and loss characteristic and extending between the first end of the first waveguide section and a first m-face facet, which is substantially perpendicular to the m-direction; and a total internal reflector surface configured at the first end of the first waveguide section to transmit light between the first waveguide section and the second waveguide section, the first waveguide section being configured in a perpendicular orientation to the second waveguide section.
