- Abstract
- Electro-optic intensity modulators at lambda =1.55 mum are produced in LiNbO3 substrates using strain-induced channel waveguides formed by magnetron deposition of a surface metal film and lift-off technology. The static strain resulting from thermal expansion mismatch between the substrate and the metal film that is caused by the plasma temperature during deposition induces a localized increase in the refractive index via the strain-optic effect. Modulation depth of 100% at a pi -rad voltage of 16.1 V is demonstrated. Electro-optic modulation behaviors in channel waveguides fabricated using strain inducing surface metal film are compared to ones formed by thick SiO2 surface film.
