All-fiber few-mode OCT using a photonic lantern (Conference Presentation)

Paper Abstract

We present here an all-fiber Few-Mode OCT system making use of a modally specific photonic lantern to simultaneously de-multiplex light exciting the first two propagation modes of a few-mode fiber. Each mode collects a distinct projection of the scattering phase function from light backscattered by the sample. This implementation is mechanically more robust, has an optimal interferometric contrast and is compatible with commercially available OCT systems. We present a proof-of-concept through the imaging of micro-beads generating varying contrast depending on their relative size. Such a system offers an additional means of intrinsic contrast for OCT.
