Fiber Bragg grating-based linear-cavity fiber laser

Optics Express, 2023
A fiber Bragg grating-based linear-cavity fiber laser is proposed and demonstrated experimentally. A single-mode fiber Bragg grating is used as a wavelength selector in the fundamental mode, and four few-mode fiber Bragg gratings are used to reflect LP01 mode, LP11 mode, LP21 mode and LP02 mode at the same wavelength.

Slow light with flat or offset band edges in multi-mode fiber with two gratings

, 2007
We consider mode coupling in multimode optical fibers using either two Bragg gratings or a Bragg grating and a long-period grating. We show that the magnitude of the band edge curvature can be controlled leading to a flat, quartic band-edge or to two ...

A Fiber Bragg Grating-Based Anemometer [PDF]

Sensors, 2018
A novel fiber anemometer based on two pairs of fiber gratings is experimentally demonstrated and can simultaneously detect wind speed and wind direction. One pair of gratings, which are separated by 90° in space, is fixed on a small stainless steel pipe driven by a rotating disc for measuring the wind-direction angle.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Three‐dimensional Antimony Sulfide Based Flat Optics

Advanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.
