Abstract: An apparatus for demultiplexing optical signals at a large number of wavelengths using at least one wavelength-selective filter includes at least two wavelength-selective filters in each case for separation of signal components at one wavelength or at two or more wavelengths, located one behind the other in an oblique configuration in the beam path of the apparatus, and disposed such that the signal component that is transmitted by a first filter falls on the subsequent, second filter, the signal component that is reflected by the second filter not being reflected back to the first filter but, instead, running past the first filter, and the signal components that are reflected by the filters are joined together.

Abstract: A glass fiber for optically coupling a light radiation source (6) to a multi-mode optical waveguide (7) includes a glass fiber core (2) for fiber-optic transmission and is enclosed in a glass-fiber wall (3). A coupling front face (4) of the core (2) is used for coupling light emitted from the light source (6) into the glass-fiber core (2) and a decoupling end-face (5) decouples the light from the glass-fiber core into the multimode optical waveguide (7)

Abstract: A plug-in connecting element is used in optoelectrical devices or subassemblies that have optical components and electrical components, and also in a plug-in connector having two plug-in connecting elements of this type. The plug-in connecting element has in a basic body, at least one electrical interface and at least one optical interface, which can be jointly connected in a pluggable manner to a matching plug-in connecting element. The plug-in connecting element is distinguished by the fact that electrical and optical paths are combined by the integration of an electrical interface and an optical interface in one plug-in connecting element.

Abstract: The optoelectronic transducer is coupled to the optical path via a focusing system comprising an optically transparent body. The body is formed in two parts (11,12) and has beam-shaping boundary surfaces. The two parts of the transparent body enclose a gas-filled cavity (13). Portions of the internal optical boundary surface form the beam-shaping boundary surfaces. The cavity may be filled with air. The beam-shaping boundary surfaces may be formed as lens surfaces, or partially lens surfaces and partially mirror surfaces.

Abstract: The multiplexer and/or demultiplexer has a transparent monolithic multiplex body (1) with 2 parallel surfaces (101,102) for multiple reflection of light, provided with a number of identical sub-groups (4-1,..4-4) for input and output of optical signals of respective wavelength, each having an optoelectronic transducer and an associated optical element, coupled to the multiplex body via a wavelength-selective filter (3).

Abstract: To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.

Abstract: A bidirectional transceiving device has a transmitting element (1) and a receiving component (4) and coupling logic (2;5) for coupling light between the transmitting element (1) and the receiving component (4) on one side and an optical waveguide (6) to be coupled on the other side. The coupling optics have two imaging systems (2,5) arranged one behind the other, so that light transmitted from the transmitting element by the first imaging system (2) is displayed in an intermediate plane (3) in which the receiving component (4) is located and thus the receiving element (4) radiates through this or passes it laterally. The second imaging system (5) displays the light from the transmitter element(1) onto the front face (61) of the waveguide (6) from the intermediate plane (3).

Abstract: The bidirectional transmitter and receiver unit includes a transmitter module (1) with an emission surface of a first size which emits light of a first wavelength. It also has a receiver module (2) with a receiver surface of a second size for receiving light of a second wavelength. A coupling lens arrangement (3) couples light between the transmitter module (1) and the receiver module (2) and also to a connected optical waveguide (4). The coupling lens includes a deflecting structure (3) which focuses the light of the first and second wavelength differently. The transmitter module (1) and the receiver module (2) are arranged next to each other or one on top of the other. The transmitter module (1) lies in the focus of the deflecting structure for the emitted wavelength and light emitted from the transmitter module, having the first wavelength, is imaged onto the end surface (42) of the optical waveguide (4).

Abstract: Laser diodes have a driver current which is dependent on aging and temperature. Emitted optical power is detected and adjusted through the use of a monitor element. However, previous transmit modules are suitable only for semiconductor lasers which emit multi-directionally. The inventive optoelectronic transmit module includes a semiconductor laser which emits unidirectionally and a monitor element. Active areas of both components point toward a coupling device. Optical coupling elements in the form of lenses and reflective elements in the form of reflective surfaces are integrated into the coupling device. The configuration of the coupling device is selected to be such that at least part of emitted radiation is passed to the monitor element, but a remaining portion penetrates the coupling device to the coupling element and is injected into or coupled-in by the latter, for example to an optical waveguide. The transmit module is particularly suitable for Vertical Cavity Surface Emitting Laser Diodes.
