Adaptive laser-tagging optofluidic microcavity for single-molecule hydrogen detection across a nine-decade concentration span
Optical microcavities are widely used as transducers for gas sensing, yet their performance is constrained by a natural trade-off between sensitivity and dynamic range. Here we introduce a laser-tagging optofluidic microcavity that overcomes this limitation, enabling hydrogen detection across a concentration range span...
