Low Loss Hollow-Core Antiresonant Fiber With Nested Elliptical Cladding Elements

open access: yesIEEE Photonics Journal, 2017
We design and investigate the optical properties of a novel hollow-core antiresonant fiber with nested elliptical cladding elements. This new structure shows low confinement loss even with a relatively small core.

Dual-wavelength domain wall solitons in a fiber ring laser

open access: yes, 2010
We report on the experimental observation of a new type of dark soliton in a fiber laser made of all normal group velocity dispersion fibers. It was shown that the soliton is formed due to the cross coupling between two different wavelength laser beams ...
