Summary

This device enables ultrafast light-by-light control without relying on nonlinearity, allowing for operation at arbitrarily low intensities.

Key Points:

- All-Optical Modulator: The modulator provides efficient control of near-infrared (750–1040 nm) femtosecond pulses, achieving contrast ratios approaching 3:1.
- High Bandwidth: It offers a modulation bandwidth exceeding 2 THz.
- Coherent Control: The device leverages the phenomenon of coherently controlled metamaterial transparency/absorption, where counter-propagating coherent beams can eliminate or totally absorb incident light.
- Low Intensity Operation: Unlike traditional nonlinear methods, this modulator operates at low intensities.
- Potential Applications: This technology paves the way for a new generation of ultrafast optical devices for data processing in coherent networks, promising significant improvements in bit rates and latency.
