ABSTRACT:
A frequency doubler of the invention employs a nonlinear optical effect of stabilizing the harmonic output from the frequency doubler. The frequency doubler has an LiNbO.sub.3 substrate, domain inverted regions and a waveguide, which are formed on the substrate, and a thin-film heater formed on the waveguide by depositing Ni-Cr. The temperature of the frequency doubler is controlled by applying a current to the thin-film heater so as to heat the frequency doubler. Even if the wavelength of a semiconductor laser is changed due to change in the environmental temperature, the frequency doubler can stably be operated by changing the temperature of the frequency doubler.
