“…Here we expand on these finding by investigating two different material systems: A neat material that consists of the multi-chromophore dendritic molecule PSLD41 [29], and a mixture of the chromophores YLD124 and PSLD41 (25:75 wt.%), also referred to as binary chromophore organic glass (BCOG) [30]. These materials are compared to a conventional guest-host material consisting of YLD124 (25 wt.%) in a PMMA matrix [17].…”

“…2(b), consists of a central connecting motif to which three EO substructures are attached (marked in green). This results in a spherical shape of the molecule, which is known to lead to an improved poling efficien y as compared to oblate and prolate structures [29], [31]. In addition, perfluoraryl containing side-groups (marked in blue) are attached to the EO substructures.…”

“…This is attributed to an increase of material conductivity during poling at high fiel strength. For low poling fields a linear relation between poling fiel and EO coefficien is expected [29], whereas for poling field beyond 200 V/μm, dielectric breakdown occurs. By linear regression of the data points obtained for low poling field E poling < 150 V/μm (red line in Fig.…”

Abstract-We report on the hybrid integration of silicon-oninsulator slot waveguides with organic electro-optic materials. We investigate and compare a polymer composite, a dendron-based material, and a binary-chromophore organic glass (BCOG). A record-high in-device electro-optic coefficient of 230 pm/V is found for the BCOG approach resulting in silicon-organic hybrid MachZehnder modulators that feature low U π L-products of down to 0.52 Vmm and support data rates of up to 40 Gbit/s.

“…Most important among them are extra-high speed electro-optic modulators, where employment of organic materials can eliminate existing physical speed restrictions of nowadays used inorganic materials [1]. From technological point of view promising are polymers and low molecular organic materials capable of forming amorphous phase or so-called organic glasses.…”

The introductory article in a series of works on the chromofore poling in thin films of organic glasses presents an overview of corona discharge applications, with a brief excursion into physics of the phenomenon. The authors consider this technique as related to the nonlinear optical (NLO) polymers. Its key points are as follows.In the ambient air such discharge is strongly affected by variable humidity and, consequently, uncertain concentration of the predominant charge carrier ((H 2 O) n H + ). To realize a repeatable poling process the composition of discharge atmosphere should be controlled (e.g. for pure nitrogen gas). In the case of discharge in N 2 the highly reactive ozone production could be avoided. To obtain second-order nonlinear activity of polymeric materials, a simple point/plane (two-electrode) technique of corona charging is successfully applied, which however does not provide information about the sample surface charge buildup and the efficiency of poling process. To study the dynamics of both the poling and the charge transport processes a three-electrode charging system -the corona triode − should be used.

D-π-A conjugated systems of two Schiff bases have been investigated using density functional theory method. Experimental observations on charge transfer (CT) using ultraviolet-visible absorption study have been verified by time-dependent density functional theory calculations. The transition corresponding to CT absorption band is found to be HOMO 0 → LUMO 0 . The HOMO-LUMO picture along with the natural bond orbital analysis show the highly delocalized CT interaction in the ring system, and it could be attributed to the large value of first order hyperpolarizability (β) at molecular level. However, owing to the lack of effective CT in the D-π-A system at molecular level, there is no effective second harmonic generation observed at solid state. But in the case of third order nonlinear optical property, the presence of strongest donor in a molecule causes the large value of second order hyperpolarizability (γ).
