Abstract

We proposed and realized an all-in-fiber polymer microdisk whispering-gallery mode (WGM) resonator, which is composed of a nanoscale polymer waveguide in conjunction with a polymer microdisk. The resonator is manufactured by femtosecond laser-induced two-photon polymerization inside a single-mode optical fiber, and its transmission spectrum has been investigated theoretically and experimentally. The WGM resonance was excited successfully, exhibiting a high factor of 2.3 × 10 at a resonant wavelength of 1416.6 nm. The temperature and humidity responses of the resonator were tested as examples of possible application. Temperature sensitivity of -96 pm/°C when the temperature increased from 25 to 60 °C and humidity sensitivity of 54 pm/%RH when the relative humidity increased from 30 to 90% were obtained. The proposed in-fiber microdisk resonator is highly suitable for detection of microorganisms, bacteria, and single molecules.

摘要

我们提出并实现了一种全光纤聚合物微盘回音壁模式（WGM）谐振器，它由纳米级聚合物波导与聚合物微盘组成。该谐振器通过飞秒激光诱导的双光子聚合在单模光纤内部制造而成，并且对其传输光谱进行了理论和实验研究。成功激发了WGM共振，在1416.6 nm的共振波长处展现出2.3×10的高品质因数。作为可能的应用示例，测试了该谐振器的温度和湿度响应。当温度从25℃升高到60℃时，温度灵敏度为-96 pm/℃；当相对湿度从30%增加到90%时，湿度灵敏度为54 pm/%RH。所提出的光纤微盘谐振器非常适合用于检测微生物、细菌和单分子。
