“…In Fig. 5, in order to determine the macroscopic second-order susceptibility (x (2) ) of the polymer sample, the SHG signal (I out ) measured from the sample was divided by the signal (I out (quartz)) measured from the reference material (quartz plate). In calculating the effective second harmonic coefficient, d 33 , correction for the absorption at 632.8 nm was made.…”

Dye-containing nonlinear optical (NLO) polymers were synthesized: (1) poly(3-(2-(3-(2-isocyanatopropan-2-yl)phenyl)-2-methylpropyl)-4-methyl-1-phenylpyrrolidine-2, 5-dione), P[(DR1,Cz)MSt-PMI], and (2) poly(9-vinyl-9H-carbazole-co-disperse red 1), PAV[DR1-Cz]. The synthesized NLO polymers were characterized by 1 H-NMR, IR, and UV -VIS spectroscopy; differential scanning calorimetry (DSC); and thermogravimetric analysis (TGA). The electro-optic (EO) coefficients (r 33 ) and their NLO properties were evaluated by simple reflection and the Maker fringe method. The EO coefficients of P[(DR1,Cz)MSt-PMI] and PAV[DR1-Cz] were measured at 632.8 nm to be 106 and 46.6 pm/V, respectively. The second harmonic generation (SHG) coefficient (d 33 ) of P[(DR1,Cz)MSt-PMI] was measured to be 71.25 pm/V.

“…1 Compared with inorganic materials, nonlinear optical polymers have a large advantage that it can be easily fabricated into optical waveguides. When some chromophores are introduced into polymer matrix, the centrosymmetry will be broken and nonlinearity will increase [2][3][4] . However, the organic chromophores will have some strong absorptions in near-infrared region due to their intrinsic bonding vibration.…”

Chalcogenide amorphous nanoparticles doped poly (methyl methacrylate) with high nonlinearity for optical waveguide

et al. 2015

Nonlinear optical polymers show promising potential applications in photonics, for example, electro-optical devices. Poly (methyl methacrylate) (PMMA) is widely used in optical waveguides, integrated optics and optical fibers. However, PMMA has not been used for nonlinear optical waveguides since it has a low nonlinear refractive index. We successfully prepared chalcogenide amorphous nanoparticles doped PMMA that had a high nonlinearity. The As 3 S 7 bulk glass was dissolved in propylamine to form a cluster solution. Then the As 3 S 7 /propylamine solution was added into methyl methacrylate (MMA) containing photoinitiator Irgacure 184 about 0.5 wt%. After well mixing the As 3 S 7 nanoparticle doped MMA was transparent. Under the irradiation by a 365 nm UV lamp, As 3 S 7 nanoparticles doped PMMA was obtained with yellow color. The third-order nonlinear optical susceptibility of As 3 S 7 nanoparticles doped PMMA was investigated. An optical waveguide array based on the As 3 S 7 nanoparticles doped PMMA composite of high nonlinearity was fabricated.

The chloride and L-tartrate salts of the 2,4-diaminoquinazolinium(1?) were prepared and characterized by both X-ray diffraction and infrared spectroscopy. The potential of the 2,4-diaminoquinazolinium(1?) cation as a building block for materials for nonlinear optics was assessed using quantum mechanical computations. Both 2,4-diaminoquinazolinium(1?) chloride dihydrate (a = 7.2121 (1) Å , b = 8.0105(2) Å , c = 18.6157(5) Å , b = 92.493(1)°, V = 1074.46(4) Å 3 , Z = 4, R = 0.0305 for 4605 observed reflections) and 2,4-diaminoquinazolinium(1?) L-tartrate dihydrate (a = 7.2899(2) Å , b = 11.9508(2) Å , c = 13.4 183(3) Å , b = 92.375(2)°, V = 1168.00(5) Å 3 , Z = 2, R = 0.0367 for 4761 observed reflections) belong to the monoclinic space group P2 1 . They are stable, nonhygroscopic, colorless and exhibit non-zero SHG efficiency for powdered samples.
