The Precision Photonic Synthesis Group at NIST is developing advanced laser technology for precise measurements and quantum applications. Their work focuses on:
1. Femtosecond laser frequency combs: These devices allow for extremely accurate measurements of optical frequencies and enable coherent frequency synthesis across a wide range of frequencies, from optical to microwave and millimeter-wave. The combs achieve an imprecision of below 1 part in 10^19.
2. Applications: The frequency combs have various important applications, including ultra-low noise microwave generation, chip-scale sensors, mid-IR molecular spectroscopy, user-defined optical waveform generation, and calibration of astronomical spectrographs for exoplanet searches.
3. Photonic links to quantum systems: The group is also developing photonic links to superconducting circuit platforms, bringing the benefits of optical systems’ high bandwidth and precise timing to quantum information systems and quantum-based voltage standards.
The work is conducted at NIST, a leading national laboratory for physical and chemical science and technology. The research aims to advance precision measurements and enable new quantum technologies.
