摘要： The present invention provides an electro-optical device comprising NLO polymer in the active layer with improved stability for light in the wavelength range of 600-1600 nm is guided through the device. The present invention is directed to an electro-optical device comprising two cladding layers and an active layer sandwiched between these cladding layers, with the active layer comprising a non-linear optically active side chain polymer with NLO-chromophores having an N-donor-delocated .pi. system-acceptor structure, the N-donor not being bonded directly to alkyl groups. There are two ways to create NLO-chromophores with N-donors which do not have adjacent linear alkyl groups: The first way is to bond one or two aromatic groups. The N-atom is further bonded to the delocated .pi. system. If only one aromatic group is present, the N-atom is, besides the delocated system, further bonded to a hydrogen or deuterium atom. The second way of avoiding adjacent alkyl groups is to employ an N-donor moiety wherein no adjacent linear alkyl groups are present.
