Model Reduction Techniques for Quantum Nonlinear Optics

November 20, 2008 - 9:45-10:10am

RLE Conference Center 36-428


Cavity quantum electrodynamics in the strong coupling regime presents various switching and self-oscillation phenomena that may be of interest for ultra-low-energy optical signal processing. A technologically interesting regime of atto-Joule characteristic energy scales can in principle be reached, corresponding to average intracavity photon numbers in the range of 10-100, but in this regime there are significant design challenges stemming from the complex interplay of quantum fluctuations with strong mean-field nonlinearities. In this talk I will provide an overview of our group's work on the development of model reduction methods for the analysis of such systems, using technical approaches borrowed from control theory and machine learning.
