Abstract
Systems and method for the delivery of a pump laser using optical diffraction are described herein. In certain embodiments, a system includes a substrate and a waveguide layer formed on the substrate. The waveguide layer includes a first waveguide of a first material configured to receive a probe laser for propagating within the first waveguide. The waveguide layer additionally includes a second waveguide configured to receive a pump laser for propagating within the second waveguide. Further, the waveguide layer includes one or more diffractors configured to direct a portion of the pump laser out of the second waveguide and through the first waveguide.
