Antisymmetric pulse generation using phase-shifted fibre Bragg grating

A 10 mm Bragg grating with a 0.18 nm (peak-to-peak) spectral response was designed to shape a train of 7 ps Gaussian pulses into antisymmetric Hermite-Gauss pulses. The pulses were characterised in the frequency and time domain. The presence of the phase shift was verified by propagation in standard fibre.
