Selective infiltration of dual-core photonic crystal fiber

Selective infiltration of air-holes in photonic crystal fibers (PCFs) with functional materials can be used to develop optical fiber devices with many advanced functions, such as asymmetric coupling, tunable beam diffraction, birefringence, high nonlinearity and short coupling length. There are four...
