A folded Fabry-Perot diplexer Of triangular shape

Authors:
Herman van de Stadt
Abstract:
In this paper we present a novel triangular, multiple-beam diplexer. Its properties are compared with existing square diplexers. Our triangular folded Fabry-Perot (FFP) diplexer is a ring-interferometer consisting of two partially-transparent mesh filters and a slightly concave mirror. The reflector is tunable in position and the three components are mounted in the shape of a triangle with 60-degree angles. The purpose of the diplexer is to superimpose a signal and a local oscillator (LO) beam with frequencies of order 1 THz and a difference frequency of order 10 GHz.
