| contents | We present a prism-coupled packaging strategy for whispering-gallery mode resonators (WGMRs). Utilizing an all-solid-state optical adhesive process with active temperature control and hermetic sealing, the package exhibits exceptional long-term stability and environmental robustness. A standalone WGMR module was characterized, demonstrating a temperature sensitivity below 10^-7 /°C and a low-frequency Z-axis acceleration sensitivity below 10^-10 /g. The module was applied as a stable optical frequency reference, achieving a short-term frequency stability of 2x10^-13 at 2 ms, and as a nonlinear photonic platform, generating Kerr soliton microcombs with a pump power of 100 mW. This compact, robust packaging solution enhances the applicability of WGMRs in real-world applications such as narrow-linewidth lasers and portable microcombs, facilitating the transition from laboratory research to practical deployment. |
