Abstract
Disclosed herein are systems and architecture for thermal waveguide-based phase shifters which improve thermal efficiency by having multi-pass waveguides arranged under the heating element in a serpentine fashion, with the waveguides having mismatched propagation constants. The combination allows for an increase in phase shift without increasing the length or the power consumption of the resistive heating element by increasing the total length of waveguide being heated by a singular heating element.
