Decomposed entropy and estimation of output power in deformed microcavity lasers
Kyu-Won Park, Kwon-Wook Son, Chang-Hyun Ju +1
Park et al. [Phys. Rev. A 106, L031504 (2022)] showed that the Shannon entropy of the probability distribution of a single random variable for far-field profiles (FFPs) in deformed…
Double exceptional points generated by the strong imaginary coupling of a non-Hermitian Hamiltonian in an optical microcavity
Kyu-Won Park, Jinuk Kim, Kabgyun Jeong
Exceptional points (EPs) have recently attracted considerable attention in the study of non-Hermitian systems and in applications such as sensors and mode switching. In particular,…
Entropic measure of directional emissions in microcavity lasers
Kyu-Won Park, Chang-Hyun Ju, Kabgyun Jeong
We propose a noble notion of the directional emission in microcavity lasers. First, Shannon entropy of the far-field profiles in the polar coordinate can quantify the degree of uni…
