The General Quantum Limit for and the Optimization of the Minimum Measurable Frequency Shift in a Laser
Selim M. Shahriar, Ruoxi Zhu, Jinyang Li +7
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 Unbalanced Interferometry for Extreme Enhancement in Sensitivity of Measuring Frequency Shift in a Laser
Ruoxi Zhu, Zifan Zhou, Jinyang Li +3
We demonstrate a slow-light augmented unbalanced Mach-Zehnder interferometer (MZI) which can be used to enhance very significantly the sensitivity of measuring the frequency shift…

Strong frequency correlation and anti-correlation between a Raman laser and its pump laser for positive and negative dispersions
Zifan Zhou, Ruoxi Zhu, Selim M. Shahriar
We show that the frequency of a Raman laser is highly correlated or anti-correlated with the frequency of the Raman pump laser, depending on whether the dispersion experienced by t…
