Reconfigurable true-time-delay lines, comprising of 2×2 thermo-optic polymer switches and rib waveguides are fabricated utilizing a combination of roll-to-roll (R2R) compatible UV imprinting and ink-jet printing, which promises high throughput and low cost photonic devices.
We demonstrate polymer based 2×2 thermo-optic switches using imprinting and print-on-demand techniques. Operation performance shows <0.5ms switching time at 1kHz. The fabrication process gives great potential for high throughput and low cost fabrication of photonic devices.
