Abstract

Photonic crystal fibers (PCF) have revolutionized the field of optical fibers. Their unique properties, as endlessly single-mode operation, high birefringence, and hollow-core optical guidance, are enabled and controlled by their hole-array geometry. Thanks to these properties, optical waveguides based on geometrically unbound PCF designs could be exploited to realize miniaturized complex devices which implement advanced photonic operations. However, arbitrary PCF geometries are difficult or even impossible to produce using current PCF fabrication methods. Here, we show how to fabricate optical waveguide segments with PCF designs by 3D microprinting and how the combination of these segments can realize complex photonic devices.
