Analytic model for the dynamics of electron trapping materials with applications in nonlinear optical signal processing

The optical mechanism and dynamics of electron-trapping material under simultaneous illumination with two wavelengths is investigated. Our analytical model proves that the equilibrium-state luminescence of such a material can be controlled to produce highly nonlinear behavior with potential applications in nonlinear optical signal processing and optical realization of nonlinear dynamical systems. Combining this new approach with state-of-the-art fast spatial light modulators and CCD cameras that can precisely control and measure exposure, large arrays of nonlinear processing elements can be accommodated in a thin film of this material.
