Extract

Recently, advanced photonic devices have been fabricated in the laboratoryand are becoming commercially available. Thus, there is considerableinterest in inexpensive but efficient non-linear optical (NLO) materialsthat are simple to make and work with. In the last three years a largenumber of publications and patents have appeared describing NLO propertiesof organic materials, usually dyes, incorporated into or syntheticallyattached to polymers [1]. Such materials must be oriented before they havesecond-order NLO activity. Two methods have been used. In one, contactpoling [2–5], two electrodes are formed on or in the material and anelectric field is placed between them. In the other, corona poling, adischarge deposits charge on the polymer, which creates a strong orientingfield [6–8]. One could generalize that contact poling is (more) difficult todo, but the results are easy to understand, while corona poling is simple todo, but the results are (more) difficult to understand. This paper describesa set of corona poling experiments.
