Abstract :
We propose and experimentally demonstrate the suitability of exploiting the dispersive feature of a chip-size delay line to perform microwave photonic filtering tasks. A band-pass microwave filter based on wavelength multiplexing which can be tuned over the 0-50 GHz spectral band is presented. The tunable delay line comprises a low-loss 1.5 mm long photonic crystal waveguide capable of generating a controllable delay exceeding 100 ps, still with limited signal attenuation and degradation.
