Optimized hourglass-shaped resonators for efficient thermal tuning of CROW filters with reduced crosstalk
We present optimized hourglass-shaped resonator CROW filters showing an improved power consumption of up to 30% when compared with standard circular ring shapes. Metal and doped waveguide heaters are compared in terms of efficiency, crosstalk and insertion losses.
