摘要：

Integrated photonic radio frequency (RF) phase shifters with de voltage control have been realized using a nested dual Mach-Zehnder modulator configuration in a hew nonlinear optical polymer, CLD2-ISX. These modulators have a V-pi of 10.8 V and exhibit excellent frequency performance measured up to 20 GHz. A near linear phase shift exceeding 108 degrees was obtained for a 16-GHz microwave signal by tuning the de control voltage over a 7.8-V range. It is expected that these integrated polymer phase shifters will find widespread applications in new types of lightweight optically controlled phased array systems.
