Tunable Laser for 1300nm O Band

Background
The National Institute of Standards and Technology (NIST) is seeking a tunable laser for the 1300 nm O band to support fundamental research in microresonator optical frequency combs. This research aims to explore photonic in-memory computing acceleration, which is critical for advancing technology in this field. The contract is issued by the Physical Measurements Lab, specifically the Time and Frequency Division and Quantum & Nanophotonics Group.
