CitationClevenson, Hannah, Pierre Desjardins, Xuetao Gan, and Dirk Englund, "Gas sensing using a resilient polymer photonic crystal nanocavity with ultra-high quality factorAbstract:We present a high-sensitivity, multi-use optical gas sensor based on a onedimensional polymer photonic crystal cavity. With an experimental Q exceeding 13100, we predict detection levels on the parts-per-billion range for a variety of gases.
