Broadband supercontinuum generation mediated by non-adiabatic mode dispersion profiles resulting in new type of soliton dynamics in dispersion-designed antiresonant hollow-core fibers is reported. A new concept of soliton explosion is demonstrated in experiment and simulation.
Antiresonant hollow core fibers (ARHCF) have low propagation loss, broad transparency windows from ultraviolet to mid-infrared regime in fundamental mode propagation and can be easily fabricated [1, 2]. In these fibers, geometrically-induced strand resonances are given by λm = 2t√n2 −1/m, where t is the strand thickness, n is the refractive index of the material and m is the integer resonance. The...
Group velocity dispersion (GVD) plays a significant role in ultra-short pulse propagation in a fiber. Advent of photonic crystal fibers made it possible to tune the fiber dispersion properties and fabricate the fibers with one or two zero dispersion wavelengths (ZDW). This work describes the successful dispersion measurement of fundamental mode in the novel antiresonant hollow core fiber (ARHCF) [1,...
We report on octave broadband supercontinuum generation from ultraviolet to near infrared wavelengths in the fundamental mode of a gas-filled novel low-loss anti-resonant hollow-core fiber having distinct transmission windows.
