Sinc-sampled fibre Bragg gratings for identical multiple wavelength operation
Through a periodic sinc modulation of the refractive index-profile in fibre Bragg gratings we demonstrate gratings with multiple equally spaced and identical wavelength channels. We show 10 cm long gratings with 4, 8 and 16 identical uniform wavelength channels separated by the ITU spacing of 100 GH...

| Summary: | Through a periodic sinc modulation of the refractive index-profile in fibre Bragg gratings we demonstrate gratings with multiple equally spaced and identical wavelength channels. We show 10 cm long gratings with 4, 8 and 16 identical uniform wavelength channels separated by the ITU spacing of 100 GHz and a 22.5 cm long grating with 4 identical dispersion compensating channels with a 200 GHz separation designed to dispersion compensate 80 km data transmission through standard fibre at 1.55 µm. |
