OSA ANU student chapter travelling lecturer– Prof. Mikhail Belkin

On the 15^th September the ANU student chapter of the OSA hosted Prof. Mikhail Belkin, from the University of Texas at Austin, as an OSA travelling lecturer.  In his talk on “Photonic devices based on quantum-engineered nonlinear metamaterials” he described how his group uses inter-sub-band transition semiconductor heterostructures to make practical photonic devices.

These devices have functionalities not available with any other technology.  For example, he described how they developed terahertz semiconductor laser sources based on efficient intra-cavity nonlinear frequency mixing in quantum cascade lasers.  He also discussed their ultrathin highly-nonlinear metasurfaces that can provide broadband focal-plane frequency up- and down-conversion in the near-mid-far-infrared with only mW-level of optical pumping.  His talk attracted a broad interest across the school and generated many discussions.
