摘要
In this paper, whispering gallery mode solvers based on a set of corresponding straight waveguide modes are proposed. The solvers project whispering gallery modes onto a linear combination of straight waveguide modes through a cavity residual operator eigensolution formalism and direct straight waveguide expansion procedures. With these implementations, a perfectly matched layer can be imposed at the cavity computation window edges automatically and optical properties of plain and metal coated silica microtoroids can be analyzed from a novel viewpoint. Additionally, the techniques can be employed in cavity mode matching methods for the modelling of cavities that strongly scatter light.
