Paper Abstract

Results of e-beam-written electro-optic (EO) organic polymeric integrated optical (IO) channel waveguide devices developed for onboard satellite applications are reported. Processing for both strip-loaded and ridge guide structures was developed to fabricate several types of devices, such as linear and curved waveguides, optical power splitters, combiners, and phase modulators, on a 3-in.-diameter silicon wafer. A large number of polished, butt-coupled devices were tested for optical loss and EO modulation at 830- and 1,310-nm wavelengths. These devices are highly reproducible, capable of very high frequency modulation (currently at 18 GHz) with a small rf drive (0 dBm), and can be made reasonably long if required. For the optical phase modulation measurements, both subcarrier modulation with phase-sensitive detection by a lock-in amplifier, and direct detection of the rf-modulated optical carrier in a lightwave analyzer, were used. The short- and long-term stability of the corona-poled EO polymer films investigated by second harmonic generation were found to be good. IO channel waveguide development considerations leading to above performance characteristics also are presented.
