1. An integrated laser diode system, comprising:

  • a first waveguide having a first reflector at a first end of the first waveguide and a second reflector at a second end of the first waveguide and an outcoupling aperture positioned to outcouple light at a location between the first reflector and second reflector of the first waveguide;

    a second waveguide having a reflector at a first end of the second waveguide, wherein a second end of the second waveguide is optically coupled to the first waveguide;

    a third waveguide having a reflector at a first end of the third waveguide, wherein a second end of the third waveguide is optically coupled to the first waveguide;

    wherein photons generated in the second and third waveguides are coupled into the first waveguide and emitted through the outcoupling aperture.
