摘要： A transmission and reception module for a bidirectional optical communication and signal transmission includes a light transmitter having a first lens coupling optical element, and a light receiver. A fiber connection has a second lens coupling optical element for a common optical waveguide. A beam splitter is disposed in a free beam path. A common housing surrounds the foregoing. The light transmitter, the beam splitter and the fiber connection as well as the light receiver which is orthogonal thereto, are disposed axially symmetrically. An optical axis of the first lens coupling optical element is axially offset from an optical axis of the light transmitter, an optical axis of the second lens coupling optical element is axially offset from the optical axis of the fiber connection, the end surface of the fiber connection, given optimal coupling-in of light, has an angle of inclination relative to its optical axis, and the beam splitter is inclined relative to an axis of symmetry of the configuration, such that backreflected radiation strikes neither a radiation-active part of the light transmitter nor a radiation-sensitive part of the light receiver.

摘要： An optical bidirectional transceiver module includes a module body having an opening, an inner hollow space and a fiber pin pushed through the opening into the inner hollow space. The fiber pin has a centric bored hole in which a light-conducting fiber is guided. A wavelength-selective filter or a beam splitter is located at a beveled end surface of the fiber pin. Radiation from an externally coupled light waveguide is emitted through the light-conducting fiber and reflected at the filter to a first optoelectronic component (transmitter). Received light radiation passes through the filter and impinges on a second optoelectronic component (receiver).

摘要： The invention relates to a method and device for determining the output power of a semiconductor laser diode being operated with a diode current. A defined measuring current, which is less than the threshold current of the semiconductor laser diode, is conducted in a conducting direction through the semiconductor laser diode. The forward voltage drop across the semiconductor laser diode is measured, and the temperature of the laser-active region of the semiconductor laser diode is determined from the measured forward voltage by using at least one calibration curve. The invention makes a simple and precise determination of the output power possible without requiring an additional measuring device, for example, a monitor diode.

摘要： An optical device includes a surface-mountable optical component with a base member having a recess filled with a transparent filler and a VCSEL element arranged in the recess. A receptacle is attached to the surface-mountable optical component. The receptacle is for receiving an optical fiber to optically connect the VCSEL element to the optical fiber. Accordingly, an inexpensive way of coupling a VCSEL element with an optical fiber is provided. In particular, the surface-mountable component can be produced using a high volume production so that the overall costs of the optical device are reduced, even if the receptacle is produced in lower numbers due to varying requirements in the way that the VCSEL will be coupled to an optical fiber.

摘要： A method and apparatus for positioning a laser diode with respect to a coupling optic for a waveguide to obtain the optimum light transmission characterized by providing a reflecting reference plane or surface extending perpendicular to the axis of the waveguide adjacent the coupling optic, projecting light through the waveguide and coupling optic onto the reflecting surface, measuring the amount of light reflected into the waveguide and adjusting the axial position of the waveguide and optic relative to the reflecting surface to obtain the optimum value, then placing the semiconductor with the facet in the reference plane and either operating the semiconductor to provide light for coupling into the waveguide and adjusting the relative positions in a transverse plane to the axis of the waveguide to obtain the optimum transmission or operating the semiconductor laser as a detector and coupling light into the waveguide at a point spaced from the laser to project into the detector and making adjustments in the transverse direction to obtain the optimum reading. The reflecting surface can be either a separate reflecting device or the facet of the laser. The apparatus includes two members each having an abutting surface with one of the members positioning the waveguide with the coupling optic to lie along an axis perpendicular to the abutting surface and the other member positioning the semiconductor laser with the facet lying in the plane of the abutting surface.

摘要： A coupling configuration for connecting an optical fiber provided with a coupling end face at one end to an optoelectronic element is described. A coupling element is disposed between the end of the optical fiber and the optoelectronic element in order to reduce back-reflections. The coupling element, which is made of an optically transmissive material, is in physical contact with the coupling end face of the optical fiber, and its side facing the optoelectronic element has a surface region which reduces back-reflections. To simplify and shorten the coupling housing, the coupling element is of lens-like configuration, for example in the form of a ball, and is held directly in the coupling housing.
