Metamaterials and metasurfaces have demonstrated many unusual properties that are useful for creating high-performance terahertz devices and components. Integration of functional materials allows metasurfaces to expand their scope of applications. Here we show that hybrid metasurfaces can provide ultrafast modulation of terahertz waves that are critical for future applications in terahertz imaging...
We demonstrate a thermo-optic switch comprising a 3.78μm-long coupled photonic crystal resonators coupled to a photonic crystal waveguide. The device has 6nm optical bandwidth, 20dB optical extinction ratio, 18.2mW switching power, and 14.8μsec rise time.
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.
