Novel Photonic Crystal Quantum Cascade Lasers Slides

Prof. Marko Lončar, Harvard University, Cambridge, MA


Abstract:  We propose a new class of Quantum Cascade (QC) lasers in which a regular array of holes is placed in the immediate vicinity of the active region of a QC laser to achieve novel functionalities.  For example, a focused ion beam is used to make holes in the facet of the laser, perpendicular to the surface of the semiconductor, to achieve distributed feedback action or to define photonic crystal micro-cavities.  In addition, these arrays of holes can have other uses, which enables innovative applications to opto-fluidics, chemical/biological sensing and nonlinear optics.


Biography:  Dr. Marko Lončar is a Postdoctoral Scholar in Applied Physics at Harvard University.  He received MS and PhD degrees from the California Institute of Technology in 1998 and 2003 respectively, and the Diploma in Engineering from the University of Belgrade (Serbia and Montenegro) in 1997.  His research interests are in the areas of micro/nano-scale photonics, quantum cascade lasers, and nano-fabrication technology.
