چکیده
Abstract The study on the excitations of whispering gallery mode (WGM) resonances optical bottle microresonator (BMR) partially coated with a thin gold Au metal film is presented. BMR was fabricated through “soften-and-compress” technique small section standard fibre. Depositing particles spheroidal curvature surface yields metal-film meniscus profile 200 nm maximum thickness and tapered edges. A polarization resolved experimental setup used to excite TE- TM-mode resonances. Coupling strengths excited WGMs would vary different coupling arrangements relative position film. Calculated Q -factor values composite TE TM were determined be in range 1800 2700, respectively.

sensor which uses whispering gallery modes (WGMs) in dielectric microspheres for biomolecular detection. The WGMs are excited by evanescent coupling to an etch-eroded single mode optical fiber. WGM resonance positions are detected as Lorentzian dips in the intensity of the fiber-transmitted light. The polarization of molecules interacting with the evanescent field of the WGM on the microsphere ...
متن کاملEnhanced evanescent coupling to whispering-gallery modes due to gold nanorods grown on the microresonator surface
The evanescent fields of whispering-gallery modes of a high-Q dielectric microresonator are locally enhanced via excitation of the surface plasmon resonances of gold nanorods grown on the microresonator’s surface. This results in enhanced coupling between the microresonator and an adjacent tapered optical fiber for frequencies in the vicinity of the surface plasmon resonance. The experimental r...
