Abstract

Wavelength-division-multiplexing (WDM) systems is the key technology for the next generation high speed optical fibre systems. Technologies for routing on a channel to channel basis in such systems are under intensive research. All-fibre channel add/drop filters with low insertion loss are required. The dominant approach is a device based on two Bragg gratings in the arms of two concatenated 3 dB fused fibre couplers [1]. The position of the two identical gratings has to be accurately controlled to provide in-phase reflection in the two arms of each coupler. This interferometric set-up requires path-length trimming during device fabrication and the correct optical phase needs to be maintained during the device lifetime.
