From the delicate patterns of snowflakes to the robust structure of diamonds, crystals are all around us. For a long time, scientists believed their growth followed a predictable path. But now, ...
Hollow-core photonic crystal fibres (HC-PCFs) represent an advanced class of optical fibres in which light is predominantly confined to an air-filled core rather than a solid glass medium. This unique ...
Hollow-core photonic crystal fibres (HC-PCFs) provide an exceptional platform for confining light within a low-index core, enabling strong light–matter interactions and precise dispersion engineering.
