Nanofiber Fabry-Perot microresonator for non-linear optics and cavity quantum electrodynamics
, 2012 We experimentally realize a Fabry-Perot-type optical microresonator near the cesium D2 line wavelength based on a tapered optical fiber, equipped with two fiber Bragg gratings which enclose a sub-wavelength diameter waist.

Photonic Microwave Filter With Steep Skirt Selectivity Based on Stimulated Brillouin Scattering
IEEE Photonics Journal, 2016 A method to enhance the filter slope of Brillouin-based photonic microwave filters is presented. This improvement is achieved by the combination of Brillouin gain and loss responses over phase-modulated signals.

Narrow Linewidth Terahertz Generation Engined by All-Fiber Parametric Optical Source
IEEE Photonics Journal, 2015 Narrow linewidth terahertz (THz) generation based on difference frequency generation pumped by an all-fiber parametric light source is reported. A pulse source with an ultra-narrow bandwidth is built up as the pump seed source for the succeeding optical ...

New Optical Solutions of the Fractional Gerdjikov-Ivanov Equation With Conformable Derivative
Frontiers in Physics, 2020 Finding exact analytic solutions to the partial equations is one of the most challenging problems in mathematical physics. Generally speaking, the exact solution to many categories of such equations can not be found.

Optical Random Riemann Waves in Integrable Turbulence [PDF]
, 2017 We examine integrable turbulence (IT) in the framework of the defocusing cubic one-dimensional nonlinear Schr\"{o}dinger equation. This is done theoretically and experimentally, by realizing an optical fiber experiment in which the defocusing Kerr ...
