Stable electro-optical or photonic device with small optical loss, resistant to relaxation after orientation

In electro-optical and photonic devices with a functional layer of oriented, cross-linked non-linear optical (NLO) polymer between 2 buffer layers, the polymer is a polyadduct (I) containing a NLO grouping, derived from (a) NLO active compound(s) (II) containing glycidyl ether or glycidyl ester grou...

Zusammenfassung:	In electro-optical and photonic devices with a functional layer of oriented, cross-linked non-linear optical (NLO) polymer between 2 buffer layers, the polymer is a polyadduct (I) containing a NLO grouping, derived from (a) NLO active compound(s) (II) containing glycidyl ether or glycidyl ester groups reacting with cyanate groups and (b) organic di- or polycyanate(s) (III).
