Abstract

Wavelength-scale defected circular microresonators with laterally confined metal layer are designed for directional emission from high Q confined modes by boundary element method (BEM), which is firstly applied to the multilayer structures. The influence of metal layer thickness on the mode filed patterns and Q factors are simulated. The results indicate that the thickness of the metal layer has a great effect on far-field emission patterns and the mode Q factors.
