This review article describes recent developments in the field of second-order nonlinear opti-
cal (NLO) polymers with specific focus on their characterization methods, materials synthe-
sis, chromophore orientation techniques, and device applications. For the characterization
techniques of NLO properties anics and polymeric materials, electric field-induced sec-
ond harmonic generation, hyper-Raleigh scattering, electro-optic coefficient measurement,
etc. are discussed. The significant progress obtained from the authors’ investigations, resulted
in various types of polymeric materials including dendrimers anic-anic hybrids
with specific structures of academic and technological significance which are presented here.
To produce highly efficient macroscopic nonlinearity in NLO polymeric systems, several
chromophore orientation techniques such as static field poling, photoassisted poling, all op-
tical poling, contact and corona poling are also demonstrated. In addition, the prospects for
practical applications of the NLO polymers in information technology are reviewed.
