Ultra-high reflectivity is achieved at the end-face of a hollow-core PCF via the insertion and fusion of a metal-coated tapered single-mode-fiber to the core of the hollow fiber. Saturable absorption is demonstrated using this device.
Optical feedback from the Fresnel reflection at the air-silica interface of a splice between a hollow core photonic crystal fiber (HC-PCF) and a conventional fiber can cause laser instability or damage. The reported solution consists of the preparation of angle cleaved fibers, spliced together using a filament fusion splicer. A reduction of 44 dB of the return loss is observed. The method will considerably...
We report on the development of all-fiber devices based on a hermetically sealed hollow-core-PCF filled with acetylene at sub-millibar pressure and designed for the generation of electromagnetically-induced transparency and for saturable absorption.
