Ultra-low Brillouin scattering in anti-resonant hollow-core fibers

APL Photonics, 2020
Sensitive optical experiments in fiber, including for applications in communications and quantum information, are limited by the noise generated when light scatters from thermally excited guided-acoustic phonons.

Low spontaneous Brillouin scattering in anti-resonant hollow-core fibers in GHz frequency range [PDF]

APL Photonics
Brillouin light scattering (BLS) is a powerful experimental tool that can be used to gain insights into the fundamental and applied properties of matter, like dispersions of quasiparticles in a solid, as well as their spatiotemporal dynamics.

Dual-core antiresonant hollow core fibers

Optics Express, 2016
In this work, dual-core antiresonant hollow core fibers (AR-HCFs) are numerically demonstrated, based on our knowledge, for the first time. Two fiber structures are proposed. One is a composite of two single-core nested nodeless AR-HCFs, exhibiting low confinement loss and a circular mode profile in each core.
