Compared with traditional inorganic second-order nonlinear optical (NLO) materials, organic
second-order NLO materials have many advantages in bandwidth, dielectric constant, half …

Polymeric electro-optic materials have recently been developed that, when fabricated into
devices such as Mach-Zehnder interferometers, permit drive (V π) voltages of less than 1 V …

The field of nonlinear optics emerged three decades ago with the development of the first
operating laser and the demonstration of frequency doubling phenomena. These milestone …

Organic Nonlinear Optical Materials provides an extensive description of the preparation
and characterization of organic materials for applications in nonlinear and electro-optics …

The potential interest of vanillin, isovanillin, thiovanillin, and isothiovanillin as starting units
for the design of hyperpolarizable molecules such as polyenovanillin (Ar-(CH= CH)„—CH …

We calculate the first hyperpolarizability (β) of several thiazole and thiophene analogues of
donor− acceptor stilbene compounds using the ZINDO (sum-over-states) formalism …

A simplifying treatment is developed for describing the molecular origins of electric dipole
allowed sum-frequency generation (SFG) and second harmonic generation (SHG). The full …

Values of the second order hyperpolarizability β have been determined for p-nitroaniline
(PNA) in solvents of varying polarity using the electric field induced second harmonic …

Publisher Summary Over the past 15–20 years, the non-linear optical (NLO) response of
organic molecules has been of wide interest to organic and physical chemists, as well as …

First hyperpolarizabilities of a large number of push− pull substituted conjugated systems
with heteroaromatic spacers have been calculated. The static, nonresonant components …
