摘      要：Silicon waveguides typically exhibit optical anisotropy,which leads to polarization correlation and single-polarization *** consequently creates a demand for polarization-control *** paper introduces a CMOS-compatible O-band reconfigurable TE/TM polarization rotator comprising two symmetrical polarization rotator-splitters and phase *** configuration enables dynamic conversion of any linear polarization to its quadratic *** results indicate that the reconfigurable polarization rotator exhibits an insertion loss of less than 1.5 ***,the bandwidth for a polarization extinction ratio beyond 15 dB exceeds 60 nm.
