Azo-type optically active compounds and polymers are provided based on compounds of the general structure [substituted aryl]--N.dbd.N--[substituted aryl] wherein aryl substituents are introduced which hinder or prohibit rotation around the single bonds of the --N.dbd.-- central moiety (as well as around certain other single bonds), to provide "planarized" structures having improved optically active properties, especially electro-optically active properties. These compounds and polymers find use in optically active waveguides.
