We present the design and fabrication of thermally-efficient tuning structures integrated into a narrowband reconfigurable radio-frequency (RF)-photonics filter using silicon-on-insulator waveguide optical delay lines. By introducing thermal isolation trenching, we are able to achieve IIR, FIR or arbitrary mixed response with less than 120 mW average tuning power in a single RF-photonic unit cell filter.
