Abstract :
Materials with large nonlinear optical (NLO) coefficients are needed for a variety of photonic applications such as: frequency doubling, optical switches and electrooptic devices. Organic chromophores have the potential to meet this need by suitable modification of their structure to optimize the hyperpolarizability, β. In particular, it has been shown that the synthesis of chromophores with large β depends on optimum tuning between the donor-acceptor strengths and the Π-electron system in bacteriorhodopsin
