Organic Electro-Optic and
All-Optical Materials and Devices
Thrust 1 Research Highlights
- Cyanine dyes with exceptional third-order nonlinear optical figures of merit for all-optical switching
Development of third-order materials suitable for AOS applications.
- Thrust on Organic Electro-Optic and All-Optical Materials and Devices
New techniques (VAPRAS and VASE) have been developed that permit definition of the order and relative orientations of various critical components of electro-optic materials.
- Thrust on Organic Electro-Optic and All-Optical Materials and Devices
Nanoscopic viscoelastic measurement techniques (FM-SP and IFA) have been developed that permit measurement of the enthalpies and entropies associated with specific spatially-anisotropicinteractions that impact poling-induced order of organic electro-optic material.
- Organic E-O Materials with Properties Tailored for Applications in High-Speed Information Processing and National Security
Exceptional properties of organic E-O materials (such as large optical nonlinearity, cryogenic temperature operation, and excellent thermal stability) have been achieved through rational molecular design of dipolar chromophores, supramolecular assembly of dendrimers, and click chemistry and controlled lattice-hardening of macromolecules.
- E-O polymer enabled low drive voltage, low loss hybrid polymer/sol-gel modulators
-
The primary achievement in this period has been the reduction of device loss (< 4dB) through the development of hybrid EO polymer/ion exchange glass modulators (1.5 cm long).
