Abstract

Apodisation-generated in-band dispersion can limit the useful bandwidth of gratings. We discuss how a trade-off in reflection squareness may be necessary in order to increase the usefull bandwidth. Introduction: Wavelength-division multiplexing (WDM) is widely recognised as the technology of choice to utilise the fibre bandwidth. The key enabling technology for WDM is grating-based filters, offering low insertion loss over a wide bandwidth and good suppression of neighbouring channels when properly designed. It has recently been discussed how the dispersion on the edges of the photonic bandgap of a grating both in-band and out-of-band can cause the reflected and transmitted signals to be significantly distorted.
In this paper we show that apodisation-induced in-band dispersion can limit the useful bandwidth of gratings considered for current transmission systems. We discuss design rules depending on apodisation and length for an optimisation of the useful bandwidth.
