Abstract

Process‐dependence characteristics of Zn‐diffused waveguides on a y‐cut, x‐propagation LiNbO~3~ substrate at 1.55‐μm wavelength are presented for the first time. The experimental results show that a single‐mode waveguide of extraordinary polarization is easily fabricated and can serve as an effective TE‐pass waveguide polarizer. The best polarization extinction ratio of 32 dB/cm and the corresponding propagation loss of 0.9 dB/cm are obtained. © 2006 Wiley Periodicals, Inc.

## Abstract A Zn‐diffused 2 × 2 balanced‐bridge optical switch is demonstrated on a Z‐cut LiNbO~3~ substrate for the first time. A post thermal‐treatment is used for precisely maintaining the 3‐dB‐power division of the two directional couplers in the device. The crosstalk ratio of both output waveg
