During a phone call, the human voice is converted to electronic signals, transmitted, and heard clearly on the other end.
The process enabling this shifting of signal frequencies is called frequency mixing, and it is essential for communication technologies like radio and Wi-Fi.
Frequency mixers are crucial components in electronic devices, operatin
Imagine a frequency mixer that operates at a quadrillion (PHz, petahertz) times per second, enabling transmission and processing of significantly larger amounts of information at much higher speeds.
MIT has demonstrated a new lightwave-electronic mixer at petahertz-scale frequencies, a first step toward making communication technology faster.
It also progresses research toward developing new, miniaturized lightwave electronic circuitry capable of handling optical signals directly at the nanoscale.
