Hollow-core fibers with ultralow loss in the ultraviolet range and sub-thermodynamic equilibrium surface-roughness
Jonas H. Osório, Foued Amrani, Frédéric Delahaye +8
We report on hollow-core fibers displaying rms core roughness under the surface capillary waves thermodynamic limit and record loss in the short-wavelength range (50.0 dB/km at 290…
Low-loss single-mode hybrid-lattice hollow-core photonic crystal fiber
Foued Amrani, Jonas H. Osório, Frédéric Delahaye +5
The remarkable recent demonstrations in ultralow loss Inhibited-Coupling (IC) hollow-core photonic crystal fibers (HCPCFs) place them as serious candidates for the next-generation…
Mid IR hollow core fiber gas laser emitting at 4.6 um
F. B. A. Aghbolagh, V. Nampoothiri, B. Debord +4
Emission at 4.6 um was observed from an N2O filled hollow core fiber laser. 8-ns pump pulses at 1.517 um excited a vibrational overtone resulting in lasing on an R and P branch fun…
Tailoring modal properties of inhibited-coupling guiding fibers by cladding modification
Jonas H. Osorio, Matthieu Chafer, Benoit Debord +8
Understanding cladding properties is crucial for designing microstructured optical fibers. This is particularly acute for Inhibited-Coupling guiding fibers because of the reliance…
