Abstract
A novel approach to ultra-narrow optical vestigial sideband (VSB) filtering based on a specially designed fibre Bragg grating (FBG) operating in transmission is proposed. This design can be easily implemented by writing FBG-based filters for each WDM channel before MUX. The specially designed filter profile allows to take full advantage of crosstalk suppression while minimising waveform distortion.
