Optical coherence tomography [1] (OCT) is an interferometric biomedical imaging technique for high resolution cross-sectional imaging of highly scattering tissue. In OCT, light sources having smooth power spectra are preferred as spectral dips result in sidelobes in the axial point spread function (PSF) that cause ghost images and mask weak axial reflections located near a strong reflection [2,3,4]. Real broadband light sources, however, often present spectral dips in their power spectra.
