AI Article Synopsis
- Researchers have successfully demonstrated nonlinear terahertz difference-frequency generation using a hybrid graphene metadevice.
- Despite previous findings that single-layer graphene cannot generate terahertz waves, this limitation has been surpassed with the injection of ultra-short optical pulses.
- This breakthrough paves the way for developing ultra-thin, nonlinear terahertz optoelectronic components.
Article Abstract
The first experimental demonstration of nonlinear terahertz difference-frequency generation in a hybrid graphene metadevice is reported. Decades of research have revealed that terahertz-wave generation is impossible in single-layer graphene. This limitation is overcome and nonlinear terahertz generation by ultra-short optical pulse injection is demonstrated. This device is an essential step toward atomically thin, nonlinear terahertz optoelectronic components.
