Abstract
A technique for implementing an all-fibre multichannel flattop filter based on an optically coherent fibre delay line structure is demonstrated. Using a cascaded high birefringence fibre structure, negative tap weighting is realised in the transversal filter with suppression of optical interference noise. Flattened passbands ~0.35 nm and 0.87 nm with ripples <0.15 dB are obtained
