摘要： A frequency agile tunable self-injection locking laser system being formed by a laser device coupled to at least one optical resonator and method and controller therefor are disclosed. A diode current and an optical resonator are controllable. A self-injection locking range is selected and the self-injection locking range corresponds an optical feedback phase for back-reflected light from the optical resonator into the laser device. A diode current is set and a maximum tuning range of the actuation voltage in which self-injection locking is maintained is determined. The laser system is operated with actuation voltages in a range depending on the determined tuning range.

摘要： The present invention relates to an electrically tunable photonic resonator device for a component having a fast and flat actuation response. The photonic resonator device includes at least one optical waveguide with an optical interface for coupling in laser light. The photonic resonator device includes at least one optical resonator including a waveguide made of an optical resonator material. A laser light coupled via the optical waveguide is coupled into at least one optical resonator. The photonic resonator device includes at least one piezo actuator to apply mechanical stress onto the optical resonator. The optical resonator, the piezo actuator, and the optical waveguide are monolithically integrated on a common substrate of the photonic resonator device. The photonic resonator device includes a mechanical mode suppression means configured to attenuate one or more mechanical modes of oscillation caused by an AC operation of the piezo actuator.
