Optimised square passband fibre Bragg grating filter with in-band flat group delay response
Through a controlled apodised sinc-shaped refractive index profile, an optimised square reflection band Bragg grating filter is demonstrated. The filter is 5cm long and has a flat dispersion profile within the photonic bandgap and an edge steepness of 7.9dB/GHz.
