Abstract:
1. A system comprising: a multiplicity of quantum dot lasers disposed on a back surface of a control circuit, wherein each of the quantum dot lasers produces coherent light; a multiplicity of micro-lens collimators, each micro-lens having a first end and a second end the first end of each micro-lens collimator secured to a corresponding quantum dot laser; and a diffraction grating; wherein light generated by the quantum dot lasers passes through the multiplicity of micro-lens collimators and is collimated when it exits at the second end of the micro-lens collimators; wherein the light from the second end of each of the micro-lens collimators is directed to the diffraction grating; and wherein the coherent light leaving the diffraction grating is a high powered optical light.
