1. An optical component, comprising:
a hollow-core photonic crystal fiber comprising a hollow core forming a non-solid space, internal capillaries for guiding radiation and located around the hollow core, and an outer capillary sheathing the internal capillaries; and
at least an output end section having a larger inner cross-sectional dimension over at least a portion of the output end section than an inner cross-sectional dimension of the outer capillary along a central portion of the hollow-core photonic crystal fiber prior to the output end section,
wherein internal capillaries of the hollow-core photonic crystal fiber are collapsed at an end of the hollow-core photonic crystal fiber such that, along a direction moving toward the end, the capillaries reduce in cross-sectional dimension while a region of the hollow core increases in cross-sectional dimension.
