摘要：

Ti-indiffused MgO:LiNbO3 (MgO:LN) waveguides for telecom wavelength band confine extraordinary light much more strongly than ordinary light. We demonstrated a polarization-selective directional coupler utilizing this characteristic. The coupler was fabricated in a Z-cut MgO (5 mol %): LN crystal by thermal diffusion of Ti stripe at 1135 degrees C for 11 h in dry Ar followed by 1 h in dry O-2. We achieved the highest extinction ratio of 13 dB. (C) 2015 The Japan Society of Applied Physics
