Abstract : This patent discloses an improved Fabry-Perot diplexer for receiving a first and second signal of differing frequency from different directions and outputting these signals in parallel relationship with respect to one another and in the same direction. The diplexer is made up of four highly reflective elements having substantially no transmission and defining an optical path therebetween. Interposed within the optical path are a pair of beamsplitters. The total length of the optical path is defined for resonance at the frequency of a first input signal and non-resonance at the frequencies of a second input signal. As a result thereof the output signals have substantially no loss associated therewith. (Author)
