Effect of Nano-architectural Control on Optical Loss in Electro-optic Polymers
Nonlinear optical chromophores have been used to obtain guest-host and side-chain polymers. The polymers are fabricated with crosslinking groups attached to both the chromophores and the polymer backbones. The guest-host composites often have micro domains that increase optical loss of the material. When the chromophore is covalently linked to the backbone, the micro domains are avoided and the optical loss of the material is decreased by a factor of 2- 3 dB/cm. This nano architectural control is crucial to produce polymer electro-optic devices that are commercially viable.
