Abstract : This document is submitted as the second annual technical report for contract No. F49620-92-C0046 and presents LPT's work on the preparation of second-order NLO composite materials. The approach employed in this work is to use NLO ormosils and sol-gel preparation techniques to produce homogeneous composite materials for fabrication of optical wave guides. The use of electric field poling technique introduces the required second-order nonlinearity which can be utilized to generate a second harmonic frequency or for high frequency light modulation. The materials that are developed exhibit sufficient nonlinearity for devices and low optical losses. The report contains a full description of the synthetic approaches, characterization and processing of the materials, the thermal and temporal stabilities of NLO responses and measurements of waveguide propagation losses.
