Title: Predicting and simulating large deviations and rare events in lightwave systems

Speaker: Jinglai Li, Institute of Natural Sciences, Shanghai Jiao Tong University

Time and place: 4:00-5:00pm, Nov 9 (Friday), 601 Pao Yue-Kong Library

Abstract:

In nonlinear lightwave systems, often the events of interest, i.e., ones that cause system errors, are large deviations of the pulses. We present a method to determine such large deviations by formulating a constrained optimization problem. We then show that the resulting optimization problem can be solved efficiently by exploiting the mathematical structure of the governing equations.

These results then guide importance-sampled Monte-Carlo simulations to determine the events' probabilities. The method applies to a general class of intensity-based optical detectors, to arbitrarily shaped and multiple pulses.
