The modulation efficiency of a tubular-lattice hollow-core fiber (HCF) employing flexural acoustic waves is investigated in detail for the first time. The main acousto-optic properties of the HCF are ...

Anti-resonant hollow core fiber (ARHCF) has the potential to guide high power laser light in a single mode without fiber damage or unwanted nonlinearities. Here, fabricated ARHCF is explored for the ...
