主 题：resonant coupling rotation
摘 要：A novel method to enhance the robustness of the microcavity coupling system(MCS)is presented by encapsulating and solidifying the MCS with a low refractive index(RI)curable UV *** encapsulating process is illustrated in detail for a typical microsphere with a radius of R about 240μ*** differences of the resonant characteristics before and after the package are observed and *** first two differences refer to the enhancement of the coupling strength and the shift of the resonant spectrum to the longer wavelength,which are both mainly because of the microsphere surrounding RI *** difference is the quality factor(Q-factor)which decreases from 7.8×10^(7)to 8.7×10^(6)after the package due to the polymer ***,rotation testing experiments have been carried out to verify the robustness of the package *** results demonstrate that the packaged MCR has much better robust performance than the un-package *** enhancement of the robustness greatly promotes the microcavity research from fundamental investigations to application fields.
