Influence of Internal Stresses in Few-Mode Fiber on the Thermal Characteristics of Regenerated Gratings

Photonic Sensors, 2019
The pre-treatment of few-mode fibers (FMFs) has been successfully done with CO2 laser. The wavelength difference, Δλ between the two resonant wavelengths in the few-mode fiber Bragg grating (FMFBG) varies with temperature increment during the annealing ...

Orbital chirality of light in few-mode step-index optical fibers

APL Photonics
A physical system is considered chiral when it can be distinguished from its mirror image, regardless of the applied translation and rotation. An electromagnetic wave can be chiral through its two essential forms of angular momenta: spin and orbital ...

Simultaneous Measurement of Chromatic and Modal Dispersion in FMFs Using Microwave Photonic Techniques

IEEE Photonics Journal, 2017
A microwave-photonic technique for measuring dispersion characteristics of few-mode fibers is proposed and experimentally demonstrated. We extract these dispersion parameters by sweeping the frequency of microwave signals modulated on an optical carrier.
