Abstract

The aim of this paper is to review our recent experimental studies on the spectral interference between two beams at the output of a Michelson interferometer and between two modes at the output of an optical fiber. The paper starts with important theoretical part in which fundamentals of the time-domain and the spectral-domain optical interferometry are applied to the two-beam and the two-mode interference experiments and then some important results of our recent experimental studies are presented. It is successfully demonstrated that the interference effects of optical beams or optical modes occur no matter how long or short the optical path difference (OPD) between beams or modes may be, so that the effect is reproduced as a periodic spatial variation when the OPD between beams or modes is shorter than the source coherence length, and as a spectral variation when the OPD between beams or modes is greater than the source coherence length. Moreover, it is successfully demonstrated that the spectral interference is resolved for both multimode and singlemode low-coherence sources. The aim of the paper is also to address some important applications of the two-beam and the two-mode spectral interferometry, including for example dispersion measurements.
