ABSTRACT:
Manufactured is a non-linear optically active (NLO) device, an optical waveguiding structure being formed which comprises at least a layer of an NLO polymer containing hyperpolarizable groups, and the NLO polymer being exposed, with heating, to an electric field for poling of the hyperpolarizable groups, the heating being by contacting the NLO polymer with a thermal energy generating live electric conductor (a resistor wire). Preferably, the live electric conductor also functions as electrode when generating the electric field with which the hyperpolarizable groups are poled. The invention further relates to a device comprising an optical waveguiding structure and electrodes for electro-optically affecting light coupled into the waveguide. The live electric conductor used in the manufacture also functions as an electro-optical effect generating electrode.
