Join the OSA Fiber Modeling and Fabrication Technical Group for a webinar featuring Philip Russell, Max-Planck-Institute for the Science of Light, discussing photonic crystal fibre and its large range of applications.
Photonic crystal fibres (PCFs) — thin strands of glass with an intricate array of hollow channels running along their length — offer an unprecedented degree of control over the guided light, making possible e.g. efficient generation of multi-octave-spanning supercontinuum light from infrared pump pulses. Chirally twisted PCF is circularly birefringent, supporting optical vortices and in some cases strong circular dichroism. Hollow-core PCFs can be designed to guide light over an extremely wide frequency range and its dispersion adjusted by varying the gas pressure in the core, providing a simple means of compressing pulses to single-cycle durations, as well as underpinning a range of unique sources of tunable deep and vacuum ultraviolet light. Particles can be trapped optically in hollow core PCFs and used to sense physical quantities with high spatial resolution. Strong optomechanical effects in solid-core PCFs have been used to robustly mode-lock fibre lasers at few-GHz frequencies.
