Abstract :
A quadrature Mach-Zehnder interferometer based on a 3 x 3 fiber coupler is presented. This novel interferometric platform is used in a homodyne configuration within an optical coherence tomography system. A fast swept laser source is used as light source. The complex interferometric signal is reconstructed so the complex conjugate ambiguity is removed. The features of this novel setup are discussed.
