Journal ArticleDOI
Side-chain liquid-crystalline copolymers containing charge transfer groups
TL;DR: A series of side-chain liquid crystal copolymers have been prepared based on a polystyrene backbone and having 4-nitro-4′-oxyazobenzenealkyloxy and 4-methoxy-4''-oxyzobenzenesene alkyloxy pendant groups as discussed by the authors.
Journal ArticleDOI
Second-order nonlinear optical properties of poled coumaromethacrylate copolymers
M. A. Mortazavi,Andre Knoesen,Stephen T. Kowel,Ronald A. Henry,James M. Hoover,Geoffrey A. Lindsay +5 more
TL;DR: In this paper, the second-order nonlinear optical properties of newly designed and synthesized coumaromethacrylate side-chain polymers are reported and the optimum poling conditions were determined experimentally.
Journal ArticleDOI
Time‐resolved waveguide modulation of a conjugated polymer
TL;DR: In this article, a pump and probe technique for measuring intensity-dependent refractive indices (n2) of waveguide quality thin films was presented, and applied to films of polydiacetylene (CH2)4OCONHOCOC4H9 (PDA•4BCMU).
Journal ArticleDOI
Technique for evaluating second-order nonlinear optical materials in powder form
TL;DR: In this paper, a technique for evaluating second-order nonlinear optical materials in powder form is described, and the power of the second-harmonic wave generated with the evanescent wave (SHEW) loosely depends on the phase matchability of material.
Journal ArticleDOI
The role of ion pairs in the second-order NLO response of 4-X-1-methylpiridinium salts.

TL;DR: The combined use of electronic absorption spectra, conductimetric measurements and pulsed field gradient spin echo (PGSE) NMR experiments show that the second-order NLO response, investigated by the electric-field-induced second harmonic generation (EFISH) technique, of the salts of the cationic NLO chromophores strongly depends upon the nature of the counter anion and concentration.
