Towards Hosting Bound State in Continuum in Specialty Optical Microcavity

Optics 2019-06-03 v1

Abstract

We exploit the interaction between supported proximity resonances in an open non-uniformly pumped optical microcavity to host a Bound State in Continuum (BIC). Using the modeling of the S-matrix, we study the coupling between the interacting states forming a BIC. We report the divergence of Quality Factor (Q-factor) of one of the interacting states, numerically demonstrated with the appropriate tuning of the spatial variation of unequal gain-loss within the system whose stability has been discussed in terms of the Petermann factor at the point of BIC. Such high lifetime has been marked as a signature of BIC.
