Abstract: | The high nonlinear photonic crystal fiber with pure silica core has been designed and fabricated, and the practical structure parameters of the fabricated fiber sample coincided precisely with the parameters we designed. The core diameter is 1.65 μm; the air hole diameter is 4.75 μm; the distance between the center of two holes is 5.35 gin; the zero dispersion wavelength of the fiber is 1120 nm; the dispersion at 800 nm is -88 ps.(nm.km)-1; and the nonlinear coefficient of this photonic supercontinuum emission with a smooth spectrum stretching from 450 to 1400 nm was attained by the injection of 30 fs Ti:sapphire laser pulses into 2 m-long high linear photonic crystal fibers, with an energy up to 5 nJ at a pulse repetition rate of 100 MHz and a central wavelength of 800 nm. |
