Electro-optic Polymers and Applications in Phase Shifters for Next Generation Phase Array Antennas

摘要

Electro-optic polymers in traveling wave modulators have the potential for very wide band operation (>100 GHz) due to the low dielectric constant of the polymers and in addition very low voltage drive requirements because of the high EQ coefficients promised by the polymer chemists. Recent advances in the understanding of dipole-dipole interactions and new techniques in modulator fabrication have resulted in modulators which realize this potential. We report here on polymer traveling wave modulators. The high thermal stability (900 deg C) and low propagation loss (1-2 dB/cm) of these devices make them commercially viable.
