Abstract :
A single mode rib waveguide (RWG) polarization modulator is described with a measured extinction ratio ≳27 dB, a power conversion ≈0.99, and a switching voltage of 12.5 V at λ = 1.064 µm. The modulator is based on a modified step delta beta-reversal configuration. Contact with CdO and an Au overlay ensures low optical losses (≲1 cm -1) for both polarizations.
