Metallic diffraction grating enhanced coupling in whispering gallery resonator
For the first time, metallic diffraction grating is investigated to enable efficient coupling in the whispering gallery resonator (WGR). Six-fold field enhancement in the resonator is achieved with respect to their dielectric counter-parts. This higher coupling efficiency is attributed to the su...

description |
For the first time, metallic diffraction grating is investigated to
enable efficient coupling in the whispering gallery resonator (WGR). Six-fold
field enhancement in the resonator is achieved with respect to their
dielectric counter-parts. This higher coupling efficiency is attributed to the
surface plasmon excitation which drives the whispering gallery mode along
the grating. Fano resonances have been observed in optical reflection. With
the metallic grating, single-port end-fire WGR configuration becomes
possible - a scheme that has not been demonstrated in any other WGR
coupling devices. Hence, it serves as a prototype for portable whispering
gallery devices potentially useful in sensing, switching and nonlinear
applications. |
