Title: A SVD-based method for determining large deformations in optical systems

Speaker: Dr. Jinglai Li, Northwestern University

Abstract:

In optical systems the events of interest, i.e., ones that cause errors, are large pulse deformations. We present a method to determine such large deformations by exploiting the mathematical structure of the governing equations and the singular value decomposition to formulate a constrained optimization problem. These results then guide importance-sampled Monte-Carlo simulations to determine the events' probabilities. The method works for a general class of intensity-based optical detectors and for arbitrarily shaped pulses.
