The thermal tuning of a Bragg grating filter on silicon-on-insulator rib waveguides has been demonstrated with integrated resistive heaters.The thermal sensitivity is 82 pm/ × - °C with an efficiency of 4.5 nm/W. A technique for indirectly measuring the temperature of the integrated heaters is also demonstrated.
