Abstract :
The authors consider the synthesis of arbitrary fibre-optic delay line filters using a modified Pade method. Although these are inherently positive systems, we show that filters with negative coefficients can be implemented by a suitable decomposition of their impulse response together with a differential photodetection scheme
