A new grain-of-rice-sized "rainbow-on-a-chip" developed by physicists at Loughborough University and international partners uses a stable optical microcomb to generate multiple high-frequency millimeter-wave signals simultaneously.
How the Technology Works
▫️Microchip Design: The device is about the size of a grain of rice.
▫️Light Spectrum: It produces a stable, precisely organized spectrum of light (a "rainbow").
▫️Millimeter Waves: An optical microcomb converts these light frequencies into multiple high-frequency electromagnetic signals.
▫️Simultaneous Data: Multiple frequencies can carry distinct data streams at the same time, vastly increasing bandwidth.
Potential Applications
▫️6G Networks: Provides the high capacity and multiple channels needed for future ultra-fast wireless communication.
▫️Quantum Tech: Offers precise timing and stability required for advanced quantum systems.
