title: Bacteriorhodopsin: a natural (nonlinear) photonic bandgap material.
abstract: The angular dependence of the hyper-Rayleigh scattered light intensity from a suspension of bacteriorhodopsin has been analyzed. The observation calls for combination of the second-order nonlinear hyperpolarizability of the retinal chromophore with the linear refractive index of the apo-protein matrix. The structuring of the small nonlinear chromophore in the large linear matrix imparts properties of a photonic bandgap to bacteriorhodopsin.
