Dynamical Husimi functions at dielectric interfaces of lasing cavities — •Tae Yoon Kwon and Martina Hentschel — MPIPKS, Dresden, Germany

We generalize the concept of Husimi functions to active optical microresonators by introducing dynamical Husimi functions at the interfaces of dielectric laser cavity systems. To this end we solve the spatio-temporal laser cavity equations, so-called Schrödinger-Bloch model, and deduce generalized, time-dependent Husimi functions. These functions give insight into the dynamics of the lasing modes in phase-space that conveniently complements the information derived from the time-dependence of the modes in configuration space. We apply these functions to characterize the near and far field optical properties of various two-dimensional microcavity systems.
