| 1. A laser device comprising:
a first waveguide having separate first order reflector gratings positioned at both ends of the first waveguide, the first
order reflector gratings further positioned on a first surface of the laser device;
a first outcoupling positioned between the first order reflector gratings, wherein the first outcoupling is located on the
first waveguide, and wherein the first outcoupling is adapted to couple light out of the first waveguide through the first
surface of the laser device;
a second waveguide having separate first order reflector gratings positioned at both ends of the second waveguide, the first
order reflector gratings further positioned on the first surface of the laser device; and
a second outcoupling positioned between the first order reflector gratings, wherein the second outcoupling is located on the
second waveguide, wherein the second outcoupling is adapted to couple light out of the second waveguide through the first
surface of the laser device, and wherein the first waveguide and the second waveguide are positioned such that the first outcoupling
and the second outcoupling overlap.
