Patent Abstract

An optoelectronic data transmission device has an active section with an active element that generates an optical gain if a forward bias is applied, and an absorption section. A waveguide incorporates the active section and the absorption section. Mirrors providing feedback for light are placed to frame the waveguide. The device can be operated in a pulsed regime emitting pulsed laser light. An additional modulator allows modulating its refractive index due to the electrooptic effect. A device providing for the modulation of the refractive index of the modulator. The refractive index of the additional modulator can be varied such that the repetition frequency of the output pulsed laser light is varied. The waveguide further incorporates the additional modulator.
