Title: NIST Develops Integrated Nonlinear Photonics for Compact Laser-Wavelength Conversion
Researchers at NIST have developed a new approach to laser-wavelength conversion using integrated nonlinear photonics, enabling compact, efficient, and reconfigurable chip-scale coherent sources. This technology could revolutionize various advanced technologies including quantum sensing, atomic clocks, and precision metrology.
The new method leverages microresonators – tiny optical cavities on a chip – to convert wavelengths from common semiconductor lasers. By engineering the resonant frequencies and dispersion properties of these microresonators, researchers can efficiently convert wavelengths to target frequencies with high efficiency.
The technology offers several key advantages over traditional bulk nonlinear systems:
– Compact and portable chip-scale devices
– High conversion efficiency
– Reconfigurable and tunable operation
– Compatibility with semiconductor laser integration
This breakthrough could enable new applications in quantum technologies, sensing, and metrology while providing a more practical and scalable solution for laser-wavelength conversion.
