Optical bistability in sideband output modes induced by squeezed vacuum

Abstract

We consider $N$ two-level atoms in a ring cavity interacting with a broadband squeezed vacuum centered at frequency ${\omega }_s$ and an input monochromatic driving field at frequency $\omega$. We show that, besides the central mode (at $ø$), many other {\em sideband modes} are produced at the output, with frequencies shifted from $\omega$ by multiples of $2(\omega -{\omega }_s)$. Here we analyze the optical bistability of the two nearest sideband modes, one red-shifted and the other blue-shifted.
