Simple and compact reflective refractometer based on tilted fiber Bragg grating inscribed in thin-core fiber
A simple and compact reflective refractometer based on a tilted fiber Bragg grating (TFBG) inscribed in an ultra-high photon-sensitive thin-core fiber is proposed and experimentally demonstrated. The reflective refractometer ...
Programmable bandwidth-variable optical temporal differentiator based on linearly chirped fiber bragg grating and digital thermal controller
We experimentally demonstrate an all-fiber structured bandwidth variable second-order optical temporal differentiator based on linearly chirped fiber Bragg grating and digital thermal controller. The bandwidth can be ...
Reflective liquid level sensor based on modes conversion in thin-core fiber incorporating titled fiber Bragg grating
A simple and compact reflective liquid level sensor based on modes conversion in the thin-core fiber incorporating one tilted fiber Bragg grating (TFBG) is proposed and experimentally demonstrated. A piece of thin-core ...
Low-timing-jitter mode-locked fiber laser based on graphene oxide pva thin film as saturable absorber
We demonstrate a mode-locked fiber laser based on graphene oxide saturable absorber at 1550nm. The laser has a timing jitter of 53fs (100Hz to 100kHz). The contribution from the slow saturable absorber is also investigated.
Laser-assisted lateral optical fiber processing for selective infiltration
We propose a new technique to perform precise selective infiltration of an air hole in the photonic crystal fiber (PCF). To carry out the infiltration process, the end face of the PCF is covered by a mask, which is fabricated ...
Design and Analysis of Microfluidic Optical Fiber Device for Refractive Index Sensing
In this letter, the microfluidic optical fiber devices composed of microchannel are modeled and thoroughly analyzed. The microchannel intersecting the fiber core allows direct infusion of surrounding substances for detection. ...
Using nonlinear optical networks for optimization: primer of the ant colony algorithm
Using nonlinear Erbium doped optical fiber network we have implemented an optimization algorithm for the famous problem of finding the shortest path on the map for the ant colony to travel to the foraging area.
