Abstract: Sapphire fiber can withstand temperatures of around 2000 °C, but it is multimoded, giving poor precision sensors. We have demonstrated a single-mode sapphire fiber Bragg grating temperature ...
Abstract: In this work, we present a high-sensitivity fiber-optic temperature sensor based on the enhanced Vernier effect. The sensor consists of a cascade of three Fabry–Perot interferometers (FPIs), ...
Demand for odor detection is growing in diverse fields such as food security, medical diagnostics, and environmental monitoring, but current technologies face limitations. Living cells with olfactory ...
