Third-order nonlinear optical figure of merits for conjugated TTF-quinone molecules

Article Abstract:

Third-order nonlinear optical figure of merits for two new TTF-molecules-TTF-diquinone(1) and TTF-monoquinone(2)-which belong to tetraathiafulvalene derivatives is studied. The result reveals that the small molecules under consideration present small absorption and their merit factor is relatively large compared to polyenic derivatives of TTF.

IR-induced second harmonic generation in Sb(sub 2)Te(sub 3)-BaF(sub 2)-PbCl(sub 2) glasses

Article Abstract:

A new type of infrared (IR) optical poling consisting of IR photopumping of appropriate electronic states is studied. It is shown that the relaxation kinetics is consistent with a simple model of electron-phonon anharmonic interactions and the technique may be used in IR optical fibers.

Temperature-pressure anomalies of electrooptic coefficients in C(sub 60)-TTF derivatives

Article Abstract:

An experiment was conducted to observe a sharplike modulation of the linear electrooptic (LEO) coefficient with pressure and temperature. The modulation depth of the LEO tensor component ion the C(sub 60)-TFF was found to be about 2.6percent.
