We have proposed and fabricated dual self-growing polymer microtips, acting as parallel Fabry-Perot interferometers (FPIs), at the end-facet of a multicore fiber (MCF). With the significantly diffe…
We present and investigate a scheme to realize fast and precise multi-characteristics extraction and error estimation of Brillouin frequency shift (BFS) simultaneously based on a cascaded feedforwa…
We experimentally demonstrate a Brillouin fiber laser (BFL) with a low threshold and narrow linewidth at 2 μ m employing a chalcogenide As 2 S 3 fiber as the Brillouin gain fiber. The As 2 S 3 fib…
A high-sensitivity low-frequency fiber-optic Fabry-Perot (F-P) acoustic sensing scheme was proposed based on optical cross-correlation (OCC). The finite element method (FEM) is used to analyze the …
A photonic-assisted scheme is proposed and demonstrated for microwave frequency down-conversion based on re-circulating opposite frequency shifting. The proposed method consists of a microwave sign…
Photonic fractional Fourier transformation (FRFT) based on discrete-frequency processing is proposed to overcome the limitations of processing latency, resolution, and tunability. Typical applicati…
Microwave photonic sensing is an emerging technology that uses broadband analog optical signal processing to help traditional optical sensor achieve higher detection speed, sensitivity, and resolut…
Optical fiber shape sensing technology provides an excellent solution for the tracking and guiding of minimally invasive surgical instruments. However, when some large-deformed instrument operation…
