Abstract:
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.
