Abstract

A previously proposed model of a molecular spatial light modulator (SLM) based on the steady state solution to a multimolecular level kinetic diagram is being extended to include time dependent phenomena. In particular the model addresses a nonlinear molecular absorber of concentration N where a write light pulse modifies the various level populations and where a read pulse interrogates this new population pattern of length L. For absorbers having a significant triplet level absorption, denoted by its crossection (sigma) ^T_ln (R), the transient contrast ratio achieved is R equals exp[2(sigma) ^T_ln(R) N L], which is the square of the steady state value.
