The process of two-photon-induced isomerization occurring in various organic molecules,
among which azobenzene derivatives hold a prominent position, offers a wide range of …

The cis− trans photoisomerization of an azo dye was induced by two-photon excitation using
a titanium: sapphire femtosecond laser, and was monitored by 1H NMR spectroscopy. The …

Reversible and non-invasive photoswitching of the immunosuppressive effect of a drug
would be a very valuable tool for precisely regulating the immune system. Using a …

We report on light induced orientation by two-photon isomerization of azobenzenes in films
of polymer. The dynamics of isomerization and orientation by one-photon absorption and …

We extend the application of the Z-scan technique to the investigation of refractive index
change associated with the photoisomerization of azobenzene polymers. The performing of …

In this paper, an all-optical switch based on asymmetric T-shaped single nanoslit coated
with Kerr nonlinear dielectric has been proposed and simulated by the finite difference time …

The Z-scan technique is used to investigate the effects of refractive index change (RIC)
associated with photoisomerization for two cases: in which the sample is pumped and …

Polarization optical anisotropy of scattering in solid-state azo-dye films induced by nonlinear
absorption has been registered for the first time. Optical anisotropy of scattering has been …

Near-resonant optical pumping was used to modulate third-order susceptibility χ (3) in
disperse red 1 doped poly (methylmethacrylate) thin films. An optically pumped degenerate …

The temperature effect on the variation of photoinduced third-harmonic generation (THG) of
an azo-polyurethane homopolymer and an azo guest–host polymer is studied at several …
