Latest Patents
Stéphane holds a patent for a narrow linewidth semiconductor laser device. This device features a semiconductor laser and a low noise current source that is operatively connected to the laser. The current source is designed to prevent degradation of the laser's frequency noise spectrum. An optical frequency discriminator provides an error signal that represents the laser's optical frequency. The control circuit includes a feedback network that adapts to both the frequency noise spectrum of the frequency discriminator and the laser's frequency noise spectrum. Additionally, the control circuit has a sequencer that automatically enables frequency locking of the laser on the frequency reference of the optical frequency discriminator. The enclosure of the frequency discriminator isolates it from external perturbations, resulting in an improved sub-kHz linewidth and high coherence while maintaining a compact, lightweight, and highly reliable design.
