Аннотация:The mechanism of optical second-harmonic generation (SHG) in thin solid oriented and nonoriented films of
bacteriorhodopsin (bR) is studied. The role of the random spatial inhomogeneity of the quadratic susceptibility
in the mechanism of diffuse and depolarized SHG in thin solid bR films is discussed. A hyper-Rayleigh
scattering formalism is used for the description of SHG in these films. Electroinduced and photoinduced effects
in SHG are detected, and the saturated concentrations of the electroinduced and the photoinduced spectral
forms of this type of bR film are estimated. Nondestructive SHG readout of bR-based optical memories is
suggested.
