Department of Electrical and Computer Engineering, University of Victoria, Victoria, BC
Opt Express 17:5311-20. 2009..In the visible regime, the effective index increases to over 10 for the same structure. The influence of symmetry-breaking in the eccentric coaxial structure is discussed as a way to enhance the local field and improve optical coupling...
