Controllable Anomalous Dispersion and Group Index Nulling via Bi-Frequency Raman Gain in Rb Vapor for application to Ultraprecision Rotation Sensing
G. S. Pati, Renu Tripathi, M. Messall +2
We have recently proposed [9], the use of fast-light media to obtain ultrahigh precision rotation sensing capabilities. The scheme relies on producing a critically anomalous disper…
Experimental Constraints of Using Slow-Light in Sodium Vapor for Light-Drag Enhanced Relative Rotation Sensing
Renu Tripathi, G. S. Pati, M. Messall +2
We report on experimental observation of electromagnetically induced transparency and slow-light (vg ~ c/607) in atomic sodium vapor, as a potential medium for a recently proposed…
Enhancement of interferometric precision using fast light
M. S. Shahriar, R. Tripathi, G. S. Pati +3
We show that anomalous dispersion characteristic of fast-light can be used to enhance the sensitivity of optical interferometry under certain conditions. In particular, we show tha…
Ultrahigh Precision Absolute and Relative Rotation Sensing using Fast and Slow Light
M. S. Shahriar, G. S. Pati, R. Tripathi +3
We describe a resonator based optical gyroscope whose sensitivity for measuring absolute rotation is enhanced via use of the anomalous dispersion characteristic of superluminal lig…
