Compact multiplexer/demultiplexer

摘要

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 (8) with at least one wavelength-sensitive element (11), a focussing member (13) with at least two focussing elements (14, 14′) as well as a detector or signal-generator plate (1), on which at least two detectors (4) or signal generators are arranged. To achieve this object, it is proposed according to the invention that both carrier plate (8) and focussing member (13) are connected to the detector or signal-generator plate (1).

1. Multiplexer/demultiplexer with a connection for inputting and/or outputting an optical signal having signal components of different wavelengths, a carrier plate (8) with at least one wavelength-sensitive element (11), a focussing member (13) with at least two focussing elements (14, 14′) and a detector or signal-generator plate (1), on which at least two detectors (4) or signal generators are arranged, characterized in that both the carrier plate (8) and the focussing member (13) are connected to the detector or signal-generator plate (1) and the focussing member (13) is formed as a shaped part, wherein the focussing elements (14, 14′) are formed integrally with the shaped part and have curved reflecting surfaces, further characterized in that the detector or signal-generator plate (1) and/or the carrier plate (8) has at least one spacer element (6, 7), wherein the at least one spacer element (6, 7) is arranged such that a gap is formed between detector or signal-generator plate (1) and carrier plate (8), and also characterized in that electric connections of the detectors are arranged inside the gap.
