NIST Innovation: Massively Tunable Frequency-Agile Lasers (nist.gov)

• Chip-scale microresonators provide precise wavelength tuning.
• Significant reduction in hardware footprint and costs for precision optics.
• Enables advanced scalability in quantum information processing.

"NIST researchers have engineered a breakthrough in laser technology, enabling the creation of devices capable of outputting almost any desired wavelength using chip-scale microresonators. By manipulating the physical dimensions of these on-chip components, researchers can precisely control light emissions. This innovation reduces the need for expensive, bulky, single-wavelength hardware, paving the way for highly integrated photonic circuits. The technology is critical for advancing high-speed telecommunications, chemical detection sensors, and the fundamental hardware required for future quantum computing networks."
