Optical injection locking of white light cavity based superluminal lasers
Jacob Scheuer, Zifan Zhou, Yael Sternfeld +2
Optical injection locking is a simple method for synchronizing a laser to an external laser source by injecting part of the external laser light into the cavity of the other laser.…

The General Quantum Limit for and the Optimization of the Minimum Measurable Frequency Shift in a Laser
Selim M. Shahriar, Ruoxi Zhu, Jinyang Li +1
We show that, contrary to conventional understanding, the minimum measurable frequency shift (MMFS) for a single-mode ideal laser is determined by a combination of phase diffusion…

Slow Light Augmented Fabry-Perot Cavity for Enhanced Sensitivity in Measuring Frequency Shift
Ruoxi Zhu, Zifan Zhou, Dustin Greenwood +3
Recently, it has been shown that a slow-light augmented unbalanced Mach-Zehnder interferometer (SLAUMZI) can be used to enhance significantly the sensitivity of measuring the frequ…
