Paper Abstract

The successful synthesis of the LD-3 electrooptic polymer has resulted in a highly reliable nonlinear organic material. However, further progress has been impeded due to the fact that LD-3 films produced thus far are too thin to form useful waveguide devices. Here the formation of thick LD-3 films ranging from 1.2 micrometers to 2.4 micrometers by using cyclopentanone as the new solvent are reported. Preliminary waveguide loss studied shows a guide loss of approximately 3 dB/cm. Aimed at forming true-time-delay lines for phased- array antenna applications, optical heterodyne detection is conducted using various waveguide lengths. A heterodyne signal of a base bandwidth of 25 GHz is demonstrated with signal-to-noise ratio of 15 dB.
