Abstract
Measurements of polarization properties (polarization dependent loss and differential group delay) of a long-period grating inscribed by means of high-intensity femtosecond 264 nm pulses in an endlessly single mode photonic crystal fibre are reported. Strong modulation in the spectra of polarization dependent loss and differential group delay with periods of 2.6 nm and 1.3 nm, respectively, were found. As such an effect has not been observed in standard optical fibres, it is believed that this is due to the specific mode structure of the holey fibre used for grating fabrication.
