An optoelectronic device that includes at least one adjustable optical damping member arranged upstream of a photodetector and damps the optical radiation passing to the photodetector. The device is configured so that an electrical output of an amplifier is connected directly or indirectly to the adjustable optical damping member. An output signal of the amplifier or a control signal formed therewith drives the optical damping member, and the photodetector, the amplifier and the damping member are integrated in the same semiconductor substrate.

Optoelectronic component including a photodetector and an optical damping member to damp the optical radiation passing to the photodetector

An optoelectronic component including an optical waveguide integrated into a plane of the component. The optical waveguide configured to guide optical radiation in the plane. The component including a coupling element connected to the waveguide and coupling optical radiation into the waveguide along the main coupling path. The degree of coupling efficiency of the coupling element is less than one in respect to the main coupling path. The coupling element outputs optical loss radiation along a secondary coupling path. The optical loss radiation is proportional to the radiation transferred along the main coupling path. The optoelectronic component includes a detector connected to the coupling element that registers the optical loss radiation and produces a detector signal. The optoelectronic component includes a control unit configured to influence at least one operating variable of the optoelectronic component based on the detector signal.

Optoelectronic component

An optoelectronic component including an optical waveguide, an integrated optical resonator, in which the waveguide or at least a portion of the waveguide is arranged, and a heat source which can increase the temperature of the resonator during operation. A web region adjoins laterally the waveguide when viewed in the longitudinal direction of the waveguide. The web region forms a jacket portion of the waveguide and has a smaller thickness than the waveguide. The heat source is thermally connected to the waveguide by means of the web region.

Optoelectronic component having a resonator

An injection modulator for modulation of optical radiation, having an optical waveguide and a diode structure, having at least two p-doped semiconductor portions, at least two n-doped semiconductor portions and at least one lightly or undoped intermediate portion between the p-doped and n-doped portions. The p-doped portions when viewed in the longitudinal direction of the waveguide are offset with respect to the n-doped portions and the diode structure is arranged in a resonance-free portion of the waveguide. The p-doped portions lie on one side of the waveguide, the n-doped portions lie on the other side of the waveguide and the intermediate portion lies in the center, each portion extends transversely with respect to the waveguide longitudinal direction in the direction of the waveguide center of the waveguide and no p-doped portion when viewed in the longitudinal direction of the waveguide overlaps any n-doped portion.

Injection modulator

An electro-optic modulator for the modulation of optical radiation of a predetermined wavelength, the electro-optic modulator having at least one optical resonator in which a standing optical wave can be formed for the predetermined wavelength. In the resonator, at least two doped semiconductor sections&#x2014;as seen in the longitudinal direction of the resonator &#x2014;are arranged at a distance from one another, and the at least two doped semiconductor sections respectively lie locally at an intensity minimum of the standing optical wave.

Electro-optic modulator

An optical pulse delay generator is provided. The optical pulse delay generator includes a first optical converter which is dispersive and separates the spectral components of the incoming optical pulse in a time domain. The first optical converter generating a converted optical signal. The optical pulse delay generator also includes a modulator to modulate the converted optical signal and to generate a modulated optical signal and a second optical converter connected to the modulator. The second optical converter being dispersive for overlaying the previously separated spectral components in the time domain and generating the delayed optical output pulse. The dispersion imposed by the second optical converter has the same amount of dispersion, but the opposite sign, as the first optical converter. At least one of the first and second optical converter includes at least two waveguide resonator rings which differ in their optical length.
