概要 Breathe sensing system that incorporates waveguide gas cells has been proved to be handy for performing daily breath checks. One critical issue for high-sensitivity breath sensing has been high propag...ation loss. We previously proposed the utilization of a silica high-mesa waveguide due to its low propagation loss. However, till date, few studies have demonstrated that a certain portion of the propagation light profiles out from the waveguide that contributes to infrared absorption sensing so far. In this study, we provide experimental evidence that a certain portion of the propagation light profiles out on an actually fabricated silica high-mesa waveguide for the first time.続きを見る
