ABSTRACT:
A frequency-stabilized semiconductor laser oscillator in which a control signal derived from a modulation signal is applied to a second optical waveguide adjacent the first optical waveguide in order to make the overall optical path between both waveguides constant despite variations in the refractive index of the optical path in the first optical waveguide. The control signal may be a current signal derived by shifting the phase of the variation of the current of the modulation signal with respect to time, or a voltage signal derived by shifting the phase of the variation of the voltage of the modulation signal with respect to time. If a current control signal is used, the compensation mechanism is an increase in the carrier density in a second optical waveguide. If a voltage control signal is used, the compensation mechanism is an electro-optic variation of the refractive index in the second optical waveguide.
