Resonant Optical Circuits Based on Coupling Between Whispering Gallery Modes in Dielectric Microresonators; Final rept. 1 Oct 2005-30 Sep 2007

摘要

The project was devoted to advancing understanding of the optical properties of mesoscopic systems of coupled spherical cavities. Using numerical modeling we studied optical coupling between spherical cavities with detuned whispering gallery mode (WGMs) resonances. The results were found to be in agreement with experiments performed on size-mismatched bispheres with controllable inter-cavity gaps. We observed a new type of optical modes termed 'nanojet-induced modes' in straight chains of microspheres. Due to subwavelength sizes of the periodically focused spots and small propagation losses.
