1. A method for using an apparatus for emitting electromagnetic radiation, the method comprising:
- in a laser diode integrated with an optical device, the laser diode comprising;
a gallium and nitrogen containing substrate member having a surface region, the surface region having either a non-polar surface orientation or a semi-polar surface orientation;
N waveguide structures each overlying a different portion of the surface region and each characterized by a gain and loss, wherein;
each of the N waveguide structures is coupled to at least one immediately adjacent one of the N waveguide structures;
each of the N waveguide structures extends in a different direction than immediately adjacent ones of the N waveguide structures;
a mirror surface is arranged between each of the N waveguide structures; and
N is at least two;
emitting the electromagnetic radiation from one of the N waveguide structures.

Abstract
A laser diode having a surface region configured on either a non-polar or semi-polar orientation. The laser diode also has N waveguide structures each overlying a different portion of the surface region. Each of the N waveguide structures is coupled to at least one immediately adjacent one of the N waveguide structures and extends in a different direction than immediately adjacent ones of the N waveguide structures.
