Fiber ring laser interrogated zeolite-coated singlemode-multimode-singlemode structure for trace chemical detection.
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.
