ABSTRACTThis paper discusses the third-order nonlinear optical (NLO) properties of substituted phthalocyanines measured by time-resolved degenerate four-wave mixing at 1064 nm. The study explores optical pumping as a mechanism contributing to a large third-order optical nonlinearity in one member of this interesting class of NLO materials, PbPc(CP)4.

This paper discusses the third-order nonlinear optical (NLO) properties of metal-free, lead and transition metal phthalocyanines, as well as scandium, yttrium and lanthanide bisphthalocyanines measured by time-resolved degenerate four-wave mixing at 1064 nm. The study focuses on the structure-property relationships and explores the possible mechanisms leading to the enhanced third-order optical nonlinearity measured for this interesting class of NLO materials.

Oriented Films

Stretch-oriented cyanine-dye-doped poly(vinyl alcohol) (PVA) films were prepared at temperatures above the glass transition temperature of PVA. The optical absorption spectra of the stretch-oriented films exhibited an anisotropy. The third-order nonlinear optical susceptibilities of the stretch-oriented films were measured parallel and perpendicular to the stretching direction by the resonant femtosecond degenerate four-wave mixing (DFWM) technique, and a high anisotropic X(3) was observed for the uniaxially stretch-oriented cyanine-dye-doped PVA films.

Time-resolved DFWM experiments were performed with 150 fs pulses at 800 nm in chloroform solutions of π-conjugated molecules: p-bis(o-methylstyryl)-benzene (Bis-MSB) and a newly synthesized derivative of distyrylbenzene: an oligomer of p-phenylenevinylene substituted in the para position with electron donating alkyleneoxy group bearing the methacrylic group and an electron accepting 2-ethylhexylsulfonyl group (MTPV-SOHE monomer). The asymmetric substitution causes a red shift (24 nm) of the absorption maximum and enhancement of third-order optical susceptibility. The second hyperpolarizability derived from a quadratic dependence of the phase matched DFWM signal on concentration of MTPV-SOHE was about 6 times bigger than that in Bis-MSB.

Nonlinear Responses

ABSTRACTIn order to discern the source of the third order nonlinear optical (NLO) phenomenon both morphological and electronic considerations are required. A series of styrene copolymers with varying amounts of p-aminostyrene or p-chloromethylstyrene were prepared as anchoring sites for chemically reactive electrophilic and nucleophilic dyes. For comparison, the same dyes were incorporated into composites of polycarbonate. Preliminary degenerate four wave mixing results for all materials indicate that the copolymeric support allowed incorporation of greater amounts of electroactive units, versus composites, and hence allowed high third order nonlinear responses (X(3)/α of approximately 10−13 esu cm). Third order NLO responses were absent in some composite systems due to limited solubility and/or phase separation difficulties.

New methacrylic monomers, their polymers with benzylidene fragment were synthesized. Structures of all compounds were determined by HNMR, UV- spectroscopies. The third order nonlinear optical properties of oxazolone, thiazolidinone and thiohydantoin containing compounds were investigated in solutions using degenerate four wave mixing (DFWM) method at 532 nm.

ABSTRACTA study was made of third-order nonlinear optical susceptibilities of new tetrathiafulvalene (TTF) derivatives, using the degenerate four wave mixing (DFWM) method, as well as complex quantum chemical calculations. To understand the physical nature of the optical nonlinearities, we separated their electronic and nuclear contributions. We found that the electronic contribution to these nonlinearities predominated. Our investigations suggest that TTF may be a highly promising material for nonlinear optics (NLO).
