Abstract:This study investigates the potential of a set of pseudo-stilbene and azobenzene molecular structures to become optical frequency converters for optical communications based on a detailed exploration of the first-order molecular hyperpolarizability (βHRS), which is the microscopic counterpart of second harmonic generation (SHG). βHRS values were obtained via quantum chemical calculations using the Gaussian 16 software package in solvent and gas-phase media at different wavelengths, i.e., 1064 nm, 1310 nm, and … Show more
“…Abegăo et al explored new push–pull derivatives that simultaneously integrate pseudo-stilbene and azobenzene units in their molecular structures. 32 Their work showcasted the potential of this novel molecular design for applications in photonic crystals with NLO conversion capabilities. Previous research has demonstrated that strong charge transfer can significantly enhance the NLO response by influencing the dipole moment and hyperpolarizability of molecules.…”
Molecular motions within functionalized octupolar NLO chromophore, with photosensitive chains comprising dual-constructed azo/stilbene units. All-optical switching is initiated by linearly polarized UV light and monitored using red-light laser line.
