Abstract

Rare earth doped crystal Pr3+:Y2SiO5 has unique features, whose nonlinear response is dynamically triggered and modulated by the interaction between dressing and phonon effect. In this article, we have demonstrated the switching from two-mode bunching to anti-bunching like phenomenon of noise intensity fluctuations used for noise correlation. Here, switching in bunching phenomenon is caused by relative nonlinear phase, which is induced by self- and cross-phase modulation. In contrast with two-mode bunching, three-mode bunching case hardly follows the switching mechanism attributed to the destructive interaction among the phases of Stokes, anti-Stokes and FL signals. We also have realized switching and routing application in two and three mode bunching. Both functions (switching and routing) are controlled by manipulating temperature of cryostat and gate delay. Our experimental results provide the novel technique for switching and channel equalization ratio of about 96%. The intensity switching speed is achieved about 17 ns.
