All-optical differential current detection technique for unit protection applications [PDF]

, 2013
In this paper we demonstrate a novel, all-optical differential current protection scheme. By monitoring the optical power reflected from two matched hybrid fiber Bragg grating current sensors and using a simple optoelectronic threshold detector, an ...

Slow light with a swept-frequency source

, 2010
We introduce a new concept for stimulated-Brillouin-scattering-based slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources.

High sensitivity micro-fiber Mach-Zehnder interferometric temperature sensors with a high index ring layer [PDF]

, 2019
The influence of the high index ring layer (HIRL) in a tapered fiber Mach-Zehnder interferometer (MZI) on the interference observed, and thus on its potential applications in temperature sensing, has been investigated.

All-fiber fused directional coupler for highly efficient spatial mode conversion [PDF]

, 2014
We model and demonstrate a simple mode selective all-fiber coupler capable of exciting specific higher order modes in two- and few-mode fibres with high efficiency and purity. The coupler is based on inter-modally phase-matching the propagation constants

Fabrication of 2 kW-Level Chirped and Tilted Fiber Bragg Gratings and Mitigating Stimulated Raman Scattering in Long-Distance Delivery of High-Power Fiber Laser

Photonics, 2021
Chirped and tilted fiber Bragg gratings (CTFBGs) have attracted a lot of attention in stimulated Raman scattering (SRS) suppression of high-power fiber lasers. However, the laser power handling capacity seriously limits their applications. In this paper,

High Power-over-Fiber Feed for Radio-over-Fiber Systems with Remote Antenna Units

IOP Conference Series: Earth and Environmental Science, 2020
Abstract We experimentally demonstrated a radio-over-fiber transmission integrated with a power-over-fiber system for next generation access networks, which can drive remote antenna units and improve bandwidth utilization effectively. We have achieved high transmission performance and expanded the signal transmission capacity.
