Applications of epoxy resins in electronics and optoelectronics. Part III. Epoxy resins with nonlinear optical properties

In the review the basic problems concerning nonlinear optical properties (NLO) of the materials (classical inorganic materials, organic crystals and polymeric materials showing many advantages) were discussed. Applications of polymers make possible the preparation of thin layers (a few to a few dozen of mu m) of NLO materials which are necessary in case of integrated optics. The most attention has been paid to wide discussion of epoxy resin (EP) based NLO materials distinguishing themselves with ease of processing and orientation of optically active molecules as well as low optical losses in comparison with another polymeric materials. The methods of preparation and functional properties of EP based NLO materials, various ways cured (with amines, by light, in sol-gel system), including IPN type EP based NLO materials (Scheme B-H, Table 1) were characterized.
