Abstract
The present disclosure is directed, in general, to (1) nonlinear optical (NLO) chromophores, (2) compositions/materials/resistive layers comprising NLO chromophores, and the methods of making the compositions/materials/resistive layers comprising NLO chromophores (e.g., methods of poling and/or drying, and the like), and (3) uses of NLO chromophores in electro-optic devices (e.g., electro-optic modulators (EOMs)).
Claims15
A nonlinear optical chromophore of a general formula (I):
- wherein D represents an organic electron-donating group, A represents an organic electron-accepting group having an electron affinity greater than the electron affinity of D;
- and Π represents a Π-bridge between the organic electron-accepting group and the organic electron-donating group;
- wherein D comprises a general formula (D1):
- where R is a substituted or unsubstituted aryl, or a substituted or unsubstituted alkyl.
An electro-optic device comprising one or more resistive film, wherein the one or more resistive film each comprising a nonlinear optical chromophore dispersed and poled within a host polymer matrix, wherein the nonlinear optical chromophore of a general formula (I):
- wherein D represents an organic electron-donating group;
- A represents an organic electron-accepting group having an electron affinity greater than the electron affinity of D;
- and Π represents a Π-bridge between the organic electron-accepting group and the organic electron-donating group;
- wherein D comprises a general formula (D1):
- where R is a substituted or unsubstituted aryl, or a substituted or unsubstituted alkyl.
