Abstract

A fast response suspended core fiber optical gas sensor configuration using side-opening hole and micro-holes array structure on the thin layers is proposed. The side-opening-hole structure enables a fast filling speed of gases into the opening-up-hole region, while the micro-holes array on the thin layers ensures that gases could further diffuse into the other holes columns quickly. Meanwhile, its sensitivity could be tripled in contrast to the previous structures. Simulation results show that a diffusion limited response time of 12 s could be realized and thus move a step further toward real-time sensing applications.
