Welcome!
The Photonics Research Lab, lead by Thomas E. Murphy at the University of Maryland, conducts research related to integrated optics, nanophotonic devices, optical sensors, Terahertz photonics, nonlinear optics, ultrafast optics, microwave photonics, and optical communication systems. Our central goal is to explore new devices and techniques that improve the speed, sensitivity, resolution, and efficiency of optical communication and sensor systems.
Some recent and ongoing projects include: design and fabrication of resonant-cavity enhanced nonlinear photodetectors for ultrafast signal processing, nonlinear dynamics in optoelectronic systems, exploration of polarization dependence in nonlinear optics, ultra-linear phase modulation techniques for high-dynamic range microwave photonic communication, porous semiconductors for biological sensing and spectroscopy. Please visit our research pages to learn more about some of these projects.
Our research is supported by the National Science Foundation, Office of Naval Research, the Laboratory for Physical Sciences (LPS), and DARPA.
