Abstract
A complex-valued multi-tap tunable microwave photonic filter
based on single silicon-on-insulator microring resonator is presented. The
degree of tunability of the approach involving two, three and four taps is
theoretical and experimentally characterized, respectively. The constraints
of exploiting the optical phase transfer function of a microring resonator
aiming at implementing complex-valued multi-tap filtering schemes are
also reported. The trade-off between the degree of tunability without
changing the free spectral range and the number of taps is studied in-depth.
Different window based scenarios are evaluated for improving the filter
performance in terms of the side-lobe level.
