Abstract: In a self-pulsing multi-section laser having two DFB sections, a Fabry-Perot-like resonator formed from two reflectors and a spacer is integrated into the multi-section laser and optically coupled to at least one DFB section. The spacer has a similar layer structure to the adjacent DFB sections (D.sub.1 and D.sub.2) but not DFB grid and takes the form of a control section operable electrically separated from the DFB sections. Selection is unnecessary. The self-pulsing two-section DFB laser of the invention with an integrated control section is suitable for optical beat regeneration in high-rate communication systems.

Abstract: A Q-switched semiconductor laser is supposed to facilitate high-frequency laser modulation with low currents or voltage ranges. According to the invention, a laser of this type consists of at least one continually pumped active medium and two optically coupled resonators at least one of which is passive, both resonators having different mode combs corresponding to the Nonius principle, at least one resonator mirror taking the form of a reflector with strongly dispersive reflection characteristics in the laser wavelength range selected by the double resonator, the index of refraction of the passive resonator and/or reflector capable of being adjusted electronically. With this device, the reflectivity of the laser wavelength can be adjusted in such a way that, with a fixed effective amplification by electrical modulation of the reflectivity of the resonator reflector with strongly dispersive reflection characteristics, the laser threshold can be raised or lowered so as to switch the semiconductor laser on or off.
