Multi-gas analysis using dual-comb-driven nanomaterial-functionalized micro-fiber Bragg grating array
Detecting gas molecules is a fundamental yet remarkable capability in nature. It involves both the qualitative identification of gas species and the quantitative measurement of their concentrations. In this study, we utilized an integrated Kerr soliton microcomb to drive a network of micro-fiber Bragg grating (micro-FBG) gas detectors on a chip. Each micro-FBG was coated with a distinct nanomaterial tailored to respond to a specific gas. The system successfully identified 12 different gas components and achieved a minimum detection limit of 45 parts per billion.
