He was awarded the status of Fellow[1] in the American Physical Society,[2] after they were nominated by their Division of Laser Science in 2009,[3] for "development of a new class of broadly-tunable infrared and terahertz sources based on nonlinear-optical conversion in bulk, micro- and nano- structured media, and their application to spectroscopic studies including demonstration of electromagnetically-induced transparency in quantum wells."
