Reconstruction of tunnelling emission pattern by using Husimi function

Summary form only given. Output directionality of asymmetric optical microcavities has been widely studied revealing many interesting features. Especially the tunneling emission is now attracting many interests due to the unexpected features in the semiclassical model. We found that the tunneling emission pattern in the far-field region can be reconstructed from the outside-outgoing Husimi function corresponding to the critical line in the phase space. Using this Husimi-reconstruction model the tunnelling emission phenomenon can be studied even in the high quality factor regime in which both experimental and theoretical difficulties arise.
