Polymer-Based Electrooptical Circular-Polarization Modulator
IEEE PHOTONICS TECHNOLOGY LETTERS, 2004, 16 (1) 96~98,-0001,():
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 25dB.
