| Challenge:
Overcome strong electrostatic interaction of large dipole chromophores in NLO polymers to improve their E-O activity.
|
Approach:
Take advantage of the site isolation and self-assembling effects of dendronized polymers to improve poling efficiency.
|
Impact:
Exceptionally large E-O coefficients (4 times that of the commercial LiNbO3) will greatly facilitate device design and performance. |
