Paper Abstract

Selective opening and closing of air-holes in photonic crystal fibers (PCFs) are realized by using a femtosecond infrared laser and a CO2 laser. By heating/tapering the PCFs while pressurizing those opened holes, the birefringent properties of the PCFs can be modified. High birefringence of 3.6×10-4 and 1.5×10-3 were obtained by post-processing commercial LMA-10 and HC-1550-02 fibers.
