Abstract
Methods for fabricating a non-linear optical (NLO) film and a NLO film structure produced thereby are provided. The methods include depositing an alignment layer material on at least one surface of a substrate, aligning the molecules of the alignment layer material in a substantially uniaxial direction, and depositing a NLO film on the alignment layer material. The methods may be advantageous in that they tend to produce NLO films having relatively strong NLO properties. The methods may be further advantageous in that they are relatively simple and may be applied to a wide range of organic NLO materials.
