Recording Policryps structures in photonic crystal fibers

Policryps structures of photo-curable adhesive NOA61 and nematic liquid crystal mixture E7 have been created inside selected microchannels of photonic crystal fibers (PCF). The PCF was selectively infiltrated with the photopolymer-liquid crystal mixture for the writing of a holographic tunable grating inside specific holes of the photonic fiber. A 2um pitch grating was successfully recorded in the PCF inner holes with and without collapsing the fiber cladding. The liquid crystal is properly aligned in both cases.
