- Abstract
- 1 × 2 on/off power splitters at λ=0.63 μm have been produced in LiNbO3 substrates using strain-induced channel waveguides formed by magnetron deposition of surface metal films and lift-off technology. The static strain resulting from thermal expansion mismatch between the substrate and the metal films induces a localized increase in the refractive index via the strain-optic effect. On/off voltage of about 25 V has been demonstrated.
