1. An apparatus comprising:

  • a laser diode integrated with an optical device, the optical device including at least one of a display device, a metrology device, a communications device, a health care or surgery device, or an information technology device, the laser diode comprising;

    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;

    a first waveguide structure configured in a first direction and 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;

    a second waveguide structure coupled to the first waveguide structure, the second waveguide structure configured in a second direction and 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 third waveguide structure coupled to the second waveguide structure, the third waveguide structure configured in a third direction and overlying a third portion of the surface region, the third waveguide structure configured in the third direction being characterized by a third gain and loss, wherein the second direction is different from the third direction.
