Packaging of low-environmental-sensitivity whispering gallery mode resonators for practical applicationsOA

中文摘要

We presents a novel prism-coupled packaging strategy for whispering gallery mode resonators(WGMRs).Utilizing an all-solid-state optical adhesive process combined with active temperature control and hermetic sealing,the proposed package scheme exhibits exceptional long-term stability and environmental robustness.The standalone WGMR module was fully characterized,demonstrating a temperature sensitivity below 10−7/℃and a low-frequency Z-axis acceleration sensitivity below 10−10/g.Furthermore,the application of this module was explored as a stable optical frequency reference and a nonlinear photonic platform,achieving a short-term frequency stability of 2×10^(−13)at 2 ms and generating Kerr soliton microcombs with a pump power of 100 mW.This compact,robust,and stable packaging solution significantly enhances the immediate applicability of WGMRs in real-world applications such as narrow-linewidth lasers and portable microcombs,thereby facilitating the transition of WGMR technology from laboratory research to practical deployment.
