Abstract :
A novel optical transversal delay line signal processor based on the use of in-fibre Bragg grating reflectors as tapping elements is presented. The requirements on reflectivity mismatch are analysed, and this is accurately controlled using postprocessing techniques. Results on frequency discriminator filters using reflectively tapped optical transversal filter structures demonstrate uniform and level responses >20 GHz with notch depths >44 dB
