Experimental vacuum squeezing in rubidium vapor via self-rotation
Jonas Ries, B. Brezger, Alexander I. Lvovsky · Physical Review A · 2003
We report the generation of optical squeezed vacuum states by means of polarization self-rotation in rubidium vapor following a proposal by Matsko et al. [Phys. Rev. A 66, 043815 (2002)]. The experimental setup, involving in essence just a diode laser and a heated rubidium gas cell, is simple and easily scalable. A squeezing of $(0.85\ifmmode\pm\else\textpm\fi{}0.05)$ dB was achieved.
