Abstract :
The authors have demonstrated a passive 2*2 polarization splitter in x-cut LiNbO/sub 3/, using a hybrid Ti-indiffusion/proton-exchange technology. At a wavelength of 1530 nm, all paths exhibited an extinction ratio of better than 20 dB, with an average excess loss of 1 dB. This component can be integrated with optical filters, switches, and beam combiners to achieve polarization-independent operations.<>
