ABSTRACT:
A first optical waveguide for guiding light is formed on a substrate. A surface acoustic wave transducer for generating a surface acoustic wave which propagates along a direction in which the first optical wave guide guides the light at least partial region of the first optical waveguide, is formed on the substrate. A wavelength variable laser oscillator can be formed which is easy to control and has a fast response speed.
