The present invention relates to a multiplexer/demultiplexer with a connection for inputting and/or outputting an optical signal which has signal components of different wavelengths, a carrier plate () with at least one wavelength-sensitive element (), a focussing member () with at least two focussing elements (') as well as a detector or signal-generator plate (), on which at least two detectors () or signal generators are arranged. To achieve this object, it is proposed according to the invention that both carrier plate () and focussing member () are connected to the detector or signal-generator plate ().

Compact multiplexer/demultiplexer

The present invention relates to a multiplexer/demultiplexer with a connection for inputting and/or outputting an optical signal which has signal components of different wavelengths, a carrier plate () with at least one wavelength-sensitive element (), a focussing member () with at least two focussing elements (') as well as a detector or signal-generator plate (), on which at least two detectors () or signal generators are arranged. To achieve this, it is proposed according to the invention that the focussing member () has at least one fiber stop, preferably formed integrally with the focussing member for adjusting a waveguide, and is connected to the detector or signal-generator plate () or to the carrier plate () via an elastic connecting element ().

An optical structure comprising a first and a second component and a connecting element which connects the two components and which has at least two spring elements. The two components have an extremely high level of positional and angular accuracy relative to each other even with major fluctuations in temperature and each spring element has a spring constant at least twice as great in two respective mutually perpendicular spatial directions as in the third spatial direction perpendicular to the first two spatial directions, referred to as the elasticity direction, wherein the two spring elements have elasticity directions which do not extend parallel to each other.

Optical structure comprising elastic suspension and method of producing such a structure

The invention concerns a method for the fabrication of an optical component with at least one fiber taper receptacle and a coupled fiber taper For this, a microstructure body is first made by coating a substrate with resist, the height of the resist diminishing essentially continuously across one region of the substrate. Next, the resist is exposed to synchrotron radiation through a mask and then developed. By electroforming and molding methods, such as micro injection molding, replicas of the microstructure body are created in plastic, for example. The invention further concerns an optical component, which has at least one fiber taper receptacle and one coupled fiber taper. The fiber taper receptacle is configured as a trough with essentially rectangular cross section. The trough height and width decrease essentially continuously across at least one region.
