Quantum control of phase fluctuations in semiconductor lasers
Abstract
The semiconductor laser, arguably the most versatile member of the family of lasers, has become a technological staple of a massively interconnected, data-driven world, with its spectral purity (i.e., temporal coherence) an increasingly important figure of merit. The present work describes a conceptually fundamental “recipe” for the enhancement of coherence, predicated on direct control of the coherence-limiting process itself, the field–matter interaction. As such, it is inherently adaptable and technologically scalable. As photonic materials and fabrication techniques continue to improve, the described approach has the potential of serving as a roadmap for major and sustained improvements in coherence. With experimentally demonstrated coherence limited at 1 kHz in this work, we envision “deep” sub-kilohertz-level coherence to be soon within reach.
