Abstract

High speed optical fibre systems require the development of technologies for routing channels. All-fibre wavelength-division-multiplexing systems are currently under intense research. Currently, the dominant approach is a device based on an all-fibre Mach-Zehnder interferometer with photoimprinted Bragg gratings in its arms, which requires path-length trimming arid balanced optical phase. We report a demonstration of a novel method for an all-fibre add/drop device based on a selective fused coupler consisting of a twin-core fibre and a standard telecommunication fibre, and a single Bragg grating. The main advantages of the device arise from the fact that it is non-interferometric, which does not need critical alignment or trimming and the fused coupler and the grating are completely de-coupled. The device allows multiple wavelength-dropping by using several gratings and potential chirping, tuning and apodisation, using well-known grating technology. Loss as low as ~1.1 dB for the added and dropped channel is demonstrated with a potential to be as low as ~0.4 dB and better than 30 dB isolation is achieved between the dropped and added channels
