Series Title: Photonics and Nanophotonics
Title: 2D THz Optoelectronics
Thomas E. Murphy, University of Maryland
Abstract: The terahertz (THz) region of the electromagnetic spectrum spans the gap between optics and electronics and has historically suffered from paucity of optoelectronic devices, in large part because of inadequate optical materials that function in this spectral range. Two-dimensional materials, including graphene and a growing family of related van der Waals materials, have been shown to exhibit unusual optical and electrical properties that could enable diverse new applications in the THz regime. In this presentation, we will present some of our own research to understand and exploit 2D materials for THz optoelectronic applications, including nonlinear optical devices, THz modulation, and THz detection.
Bio: Thomas E. Murphy received bachelors degrees in Electrical Engineering and Physics from Rice University in 1994. He then studied Electrical and Computer Engineering at Massachusetts Institute of Technology, receiving the MS degree in 1997 and Ph.D degree in 2001. He was employed as a member of the technical staff at MIT Lincoln Laboratory from 2001-2002, and joined the faculty at the University of Maryland in 2002. He currently holds a joint appointment as a Professor in the Department of Electrical & Computer Engineering and Director of the Institute for Research in Electronics & Applied Physics. His research interests include terahertz and microwave photonics, two-dimensional optoelectronics, integrated optics, nonlinear and ultrafast optics, electrooptics, and nonlinear dynamical systems.
