Claims
- 1. A nonlinear optical device comprising:
an active element formed from a chromophore including an electron donor group, an electron acceptor group, and a bridge structure between the electron donor group and the electron acceptor group;
wherein the electron donor group and the bridge structure are formed as: 1wherein R=H, F, or any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group with 1-30 carbon atoms functionalized with zero or more of the following functional groups: hydroxy, ether, ester, amino, silyl, and siloxy, and R groups at different positions are not necessarily the same.
- 2. A nonlinear optical device comprising:
an active element formed from a chromophore including an electron donor group, an electron acceptor group, and a bridge structure between the electron donor group and the electron acceptor group;
wherein the bridge structure is formed as: 2wherein A is selected from CH2 and O; wherein R=H, F, or any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group with 1-30 carbon atoms functionalized with zero or more of the following functional groups: hydroxy, ether, ester, amino, silyl, and siloxy, and R groups at different positions are not necessarily the same.

- 4. A nonlinear optical device comprising:
an active element formed from a chromophore formed as: 4wherein A is selected from CH2 and O; wherein B is an electron acceptor; wherein R=H, F, or any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group with 1-30 carbon atoms functionalized with zero or more of the following functional groups: hydroxy, ether, ester, amino, silyl, and siloxy, and R groups at different positions are not necessarily the same.
- 5. The nonlinear optical device of claim 4,
wherein the electron acceptor B is selected from: 5wherein R=H, F, or any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group with 1-30 carbon atoms functionalized with zero or more of the following functional groups: hydroxy, ether, ester, amino, silyl, and siloxy, and R groups at different positions are not necessarily the same.
- 6. The nonlinear optical device of any of claims 1 to 5 wherein the device is an electro-optic modulator.
- 7. The nonlinear optical device of any of claims 1 to 5 wherein the device is a phase shifter.
