Abstract :
We demonstrate thermo-optically tunable multiple-channel micro-ring resonators as an ultra-compact on-chip spectral shaper, and tunable multiple-ring all-pass filters as variable delay lines for photonic radio-frequency waveform generation. High quality radio-frequency pulsed signals were achieved.
