A fully integrated 4-bit true time delay device using polymer optical switches and waveguide delay lines is demonstrated. The fabricated device, which contains five 2 × 2 thermo-optic switches, has a maximum power consumption of 143   mW and a switching time less than 3   ms . The rf phase error, which is affected by the optical switch cross talk, is also theoretically analyzed and proved to be negligible by experimental results.
