Abstract
The wavelength tolerance of a frequency doubler is enhanced so as to perform stable operation. Further, with the use of this frequency doubler, a laser source can directly modulate a laser. A waveguide and a periodic domain inverted layer are formed on an LiTaO.sub.3 substrate of -C plate, and the waveguide is divided into a plurality of zones having different propagation constants. A fundamental wave inputted in the waveguide is converted into a harmonic wave in each of the zones, and is emitted as SHG light. Parts for modulating the phases of the harmonic waves produced in the respective zones are provided between the zones.
