Abstract :
We present results for a broad bandwidth continuously tunable optical delay line based on the balanced side-coupled integrated space sequence of resonators scheme. A tunable delay of up to 345 ps is obtained without distortion of the optical signal. Fast thermal switching speed under 10 μs is achieved without any measurable long-term transient by utilizing a novel balanced thermal tuning scheme.
