Over the last three decades, photonic crystals (PhCs) have attracted intense interests thanks
to their broad potential applications in optics and photonics. Generally, these structures can …

Herein, various 3D additive manufacturing approaches are reviewed in terms of two
important figures of merit: maximum voxel printing rate and minimum voxel size. Voxel sizes …

Direct laser writing has become a versatile and routine tool for the mask‐free fabrication of
polymer structures with lateral linewidths down to less than 100 nm. In contrast to its planar …

A new class of composite materials has emerged which provides a means to control and
manipulate light. These materials, known as photonic crystals, are periodic arrays of …

Research into the three-dimensional nanostructuring of photopolymers by ultrashort laser
pulses has seen immense growth over the last decade. In this paper, we review the basic …
