Abstract

The far-field emission pattern of a two-dimensional circular microresonator with a point scatterer inside, at some distance away from the centre, is investigated theoretically. We demonstrate that the presence of the scatterer leads to significant enhancement in the directionality of the outgoing light in comparison with whispering gallery modes of a circular resonator without scatterer. Numerical results show that the highly directional modes are observed in various frequency regions depending on the position and strength of the scatterer.
