Abstract
Novel acceptor-donor-acceptor and donor-acceptor-donor compounds for use in forming a thermally-stable electro-optic waveguide are disclosed. Also disclosed is a thermally stable waveguide material containing thermally stable acceptor-donor-acceptor or donor-acceptor-donor guest dipole compounds in a temperature-resistant polymer matrix. The waveguide has selected regions in which the net dipoles of the guest molecules are oriented, for electro-optic switching when an electric field is placed across these regions.
Claims11
A compound having a structure selected from the group consisting of ##STR6## wherein X is O, S, CH.sub.2, or NR, where R is a lower alkyl group;
- Y.sub.1, Y.sub.2, Y.sub.3 and Y.sub.4 are separately H or OH, where at least one of Y.sub.1 and Y.sub.2 is OH;
- and m, n, o and p are separately integers from 2 to 7.
A compound having the form:
- ##STR7## wherein Ar is an aromatic fused ring structure having a ring-contained tertiary amine, and R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are the same or different and are each selected from the group consisting of H, an alkyl group or a substituted alkyl group.
