...By contrast, low-cost polymer materials such as polydimethylsiloxane (PDMS) [21], polymethyl methacrylate (PMMA) [22], and UV-curable adhesive [23], with the attributes of low attenuation loss, good chemical stability, and broadband transmission, can be flexibly used to fabricate optical microcavities of different structures with or without a master....

...Since Norland Optical Adhesive 61 (NOA 61), one of the UV-curable adhesives, has been successfully demonstrated to fabricate WGM microsphere resonators in our previous work [23] and the surface energy of NOA 61 (40 dynes∕cm [24]) is much less than the surface energy of glass fiber (500 dynes∕cm [25]), the NOA 61 can wet the optical fiber and form a prolate structure under the action of interfacial tension....
