Wearable sensing devices, which can find tremendous applications in healthcare and automation, are attracting great attention in recent years. Herein, we report a flexible wearable optical sensor (…
Photothermal actuation that leverages optical fiber and plasmonic materials would not only add a practical function but also spur many important applications for the fiber-optic sensors, for exampl…
A novel fast-response sensitivity-enhanced high-temperature all-fiber Fabry–Pérot high-pressure sensor formed with a hard-core diaphragm is proposed and demonstrated. The structure can effective…
We demonstrate an RF photonic fractional Hilbert transformer based on an integrated Kerr micro-comb source featuring a record low free spectral range of 48.9 GHz, yielding 75 microcomb lines across…
Near-visible fiber Bragg grating finds myriad of applications such as quantum sensing, biomedical detection, and portable fiber probe. However, handling the requirements of flexibility, efficiency,…
Product-fit uncertainty is cited as one of the top reasons for high online product return rates. Fit describes how well a product suits a consumer’s needs. The value of a product drops sharply wh…
We propose two types of temperature-compensated all-fiber sensors based on a novel laser-machined Fabry-Perot interferometer (FPI) whose sensitivity is adjusted by controlling the FPI gauge length …
We propose and experimentally demonstrate a highly flexible and applicable configuration, namely, the “vertical-fluid-array induced optic microfiber long period grating” (VIOLIN), for fully exp…
