  journal={arXiv: Optics},
We report on a strong and tunable magnetic optical nonlinear response of Bacteriorhodopsin (BR) under "off resonance" femtosecond (fs) pulse excitation, by detecting the polarization map of the noncollinear second harmonic signal of an oriented BR film, as a function of the input beam power. BR is a light-driven proton pump with a unique photochemistry initiated by the all trans retinal chromophore embedded in the protein. An elegant application of this photonic molecular machine has been… 


Bacteriorhodopsin: a natural, efficient (nonlinear) photonic crystal
From the angular dependence of the second-order nonlinear light scattering (hyper-Rayleigh scattering) from a suspension of purple membrane, bacteriorhodopsin was recently shown to exhibit
Mechanism of the chiral SHG activity of bacteriorhodopsin films.
The calculations indicated negligible chirality with the tensor for the PSB retinal chromophore, but significant chiral-specific activity for the thin film through a relatively simple orientational mechanism.
Optical chirality of bacteriorhodopsin films via second harmonic Maker’s fringes measurements
We experimentally investigated second harmonic generation from an oriented multilayer film of bacteriorhodopsin protein, deposited onto a charged surface. The generated signal is obtained as a
Optical limiting by chemically enhanced bacteriorhodopsin films.
The optical limiting properties of a thin film (~150 microm) of chemically enhanced bacteriorhodopsin under cw laser illumination is investigated. The effective nonlinearity n(2) of the film is
Hyper-Rayleigh light scattering from an aqueous suspension of purple membrane.
This work reports the first observation of hyper-Rayleigh light scattering from bacteriorhodopsin in the form of an aqueous suspension of unoriented purple membranes and proposes that the 532-nm scattered light from each of the bacteriorodopsin molecules in a single purple membrane is coherent, and that the scattered lightFrom different purple membranes is incoherent.
Mapping the nonlinear optical susceptibility by noncollinear second-harmonic generation.
A method, based on noncollinear second-harmonic generation, to evaluate the nonzero elements of the nonlinear optical susceptibility, which is useful when the generated signal is strongly affected by sample rotation.
A unifying concept for ion translocation by retinal proteins
Two results can be explained by and are discussed in light of the new hypothesis: structural changes in either molecule lead to a change in ion affinity and accessibility for determining the vectoriality of the transport through the two proteins.
One‐electron second‐order optical activity of a helix
The second‐order nonlinear‐optical response of a chiral molecule is calculated. We model the optical response classically using a single electron bound to a helical path. The helical motion of the
Bacteriorhodopsin intermediate spectra determined over a wide pH range
The pH dependence of the absorption spectra of bacteriorhodopsin and its photocycle intermediates was studied in the pH range 4.5-9. The spectra of the intermediates were determined from difference
