Summary
We developed a novel electro-optic (EO) polymer/silicon hybrid metasurface modulator achieving 118 GHz bandwidth. This high-speed, low-power device enables data rates up to 300 Gbps for advanced optical communication.
Area of Science:
- Photonics and Metamaterials
- Optoelectronics
- Materials Science
Background:
- Metasurfaces enable novel, ultrathin, and compact photonic devices.
- Achieving electrically tunable, high-speed metasurfaces remains a significant challenge in the field.
Purpose of the Study:
- To present an electro-optic (EO) polymer/silicon hybrid metasurface modulator.
- To demonstrate high-speed modulation capabilities and a significant extinction ratio.
Main Methods:
- Designed a metasurface with broken in-plane inversion symmetry to generate a high-quality (high-Q) resonance.
- Utilized an EO polymer/silicon hybrid structure for enhanced modulation.
- Simulated modulation bandwidth and extinction ratio under specific driving voltage.
Main Results:
- Achieved an estimated 3dB modulation bandwidth of up to 118 GHz.
- Verified a 16 dB extinction ratio under a driving voltage of 4V.
- Demonstrated ultra-fast single-lane data rates up to 300 Gbps with low RF power.
Conclusions:
- The developed hybrid metasurface modulator offers high-speed and low-energy performance.
- Potential applications include intelligent tunable metasurfaces and space optical communication.
