Abstract: This manuscript introduces the development of various forms of photonic crystal fibers (PCFs), including hexagonal, square, and circular structural shapes. The hexagonal and square ...

Researchers at NYU have developed a way to use light to precisely direct how microscopic particles assemble into crystals.

Every crystal's shape is a mirror of the internal arrangement of its molecules, but the molecules in photoswitchable crystals can expand, twist and change properties—from their color to their ...
