Abstract

A number of researchers have conducted investigations to demonstrate Zeno switching through inverse Raman scattering (IRS) in optical fiber. Zeno switching refers to switching of a signal optical beam in the presence of a control-pump beam in which neither beam is separately absorbed. Light at the anti-Stokes frequency is strongly attenuated in the presence of a pump field. The switching contrast that is determined by the observed level of induced absorption via IRS in the optical fiber is more than 20 dB in a time scale of less than 5 ps. Researchers have extracted the full Raman response function experimentally and found excellent agreement between theory and experiment. IRS has also been found to be a good candidate to build a Zeno-type all-optical switch due to specific scattering characteristics.
