Radially graded index whispering gallery mode resonator for penetration enhancement

Radially graded index whispering gallery mode resonator for penetration enhancement

This paper theoretically analyzes a hollow cylindrical whispering gallery mode resonator with radially inhomogeneous cladding. We propose an index profile of n(r) = b/r to enhance field penetration towards the resonator core. With such index profile, externally coupled evanescent wave can easily pen...
