Semiconductor lasers, invented 60 years ago, as as a solution looking for a problem, are now everywhere, with estimated market size of $10 billion in a few years. However, trade-offs are needed for these traditional semiconductor lasers to achieve all three requirements: high power, high speed, and high beam quality. Based on advanced in nanophotonics and nanomanufacturing, the Semergytech technology addresses this fundamental challenge by offering a compact semiconductor chip solution with high power, high speed, and high beam quality, without much compromises and trade-offs. It can have implications in laser communications (space satellite, e.g.), in LiDAR, in laser manufacturing, and in directed energy. References: W. Zhou and M. Pan, US Provisional Patent (pending) W.
