F. Bakhti et al., Grating-assisted Mach-Zehnder OADM using photosensitive-cladding fibre forcladding mode coupling reduction, ELECTR LETT, 35(12), 1999, pp. 1013-1014
The realisation and systems performance of an OADM based on a grating-assis
ted Mach-Zehnder interferometer imprinted on photosensitive-cladding fibre
are reported. This component provides low short wavelength losses, a high r
erum loss at the input port. low chromatic dispersion and low PMD. A thorou
gh characterisation is presented of the device and its system performance f
or multiwavelength transmission at 10Gbit/s per channel, showing compatibil
ity with 50GHz grid dense WDM systems.
