Abstract :
An integrated circular-polarization modulator (CPM) is designed and fabricated with electrooptic (EO) polymeric materials employing contact poling. Tilted-poling is employed to activate the conversion between TE and TM modes, while the tensor nature of the poled polymeric materials is used to generate the phase-difference modulation. With appropriate voltage control, the outputs at the 45°-tilted linear, left-hand-circular (LHC), -45°-tilted linear, and right-hand-circular (RHC) polarization states are achieved. The extinction ratios at the linearly polarized states are larger than 25 dB.
