Abstract
A monolithically integrated optical device. The device has a gallium and nitrogen containing substrate member having a surface region configured on either a non-polar or semi-polar orientation. The device also has a first waveguide structure configured in a first direction overlying a first portion of the surface region. The device also has a second waveguide structure integrally configured with the first waveguide structure. The first direction is substantially perpendicular to the second direction.

A method of manufacturing a monolithically integrated optical device, the method comprising:
- providing a gallium and nitrogen containing substrate member having a surface region, the surface region being configured on either a non-polar surface orientation or a semi-polar surface orientation;
- forming a first waveguide structure configured in a first direction overlying a first portion of the surface region, the first waveguide structure configured in the first direction being characterized by a first gain and loss;
- and
- forming a second waveguide structure configured in a second direction overlying a second portion of the surface region, the second waveguide structure configured in the second direction being characterized by a second gain and loss,
- wherein the first direction is different from the second direction.
A monolithically integrated optical device comprising:
- a gallium and nitrogen containing substrate member having a surface region, the surface region configured on either a non-polar orientation or a semi-polar orientation;
