Future large-scale integrated photonic system demands materials and devices at atomic scales with virtually zero-energy consumption. Over the years, we have been working on a wide range of semiconductor materials towards compact nano-scale lasers, sensors, and bio-compactible photonic components. In this talk, we will report some recent advances on buried tunnel junction based quantum well lasers on silicon, photonic crystal cavity integrated single sheet lasers, and flexible/bio-compactible optical sensors. The potentials and challenges associated with crystalline semiconductor nanomembranes and monolayer 2D materials will also be discussed.
Professor Weidong Zhou obtained BS and ME degrees from Tsinghua University, Beijing, China, and PhD degree in Electrical Engineering from University of Michigan, Ann Arbor. He worked at CIENA corporation for three years before joining University of Texas at Arlington. He is currently a Distinguished University Professor of Electrical Engineering, working on semiconductor optoelectronics and nanophotonic materials and devices Dr. Zhou and his group have been working in the area of photonic crystal membrane photonics, especially membrane lasers and imagers, for integrated silicon photonics and flexible optoelectronics. Dr. Zhou is a fellow of SPIE, a senior member of IEEE, and a member of OSA, APS, MRS, and AAAS. Dr. Zhou’s major awards include Member of UTA Academy of Distinguished Scholars (2016), UTA Outstanding Research Achievement Award (2015), College of Engineering Excellence in Research Award (2013), etc.
