Zeolite thin films were synthesized on the claddingless multimode portion of a singlemode-multimode-singlemode (SMS) fiber structure to construct a chemical vapor sensor. The zeolite-coated SMS structure was inserted into a fiber ring amplifier to produce a laser line. Combining the strong molecular adsorption capability of the nanoporous zeolite and the high signal-to-noise ratio of the fiber laser, the device was demonstrated for chemical vapor sensing with a low detection limit.
沸石薄膜在单模-多模-单模（SMS）光纤结构的无包层多模部分上合成，以构建化学气相传感器。沸石涂层的 SMS 结构被插入光纤环形放大器中以产生激光线。结合纳米多孔沸石的强分子吸附能力和光纤激光的高信噪比，该器件在化学气相传感方面表现出低检测限。
