Abstract

Multimodal optical coherence tomography (OCT) can be implemented using double-clad fiber (DCF). A consequence of using DCF is the introduction of multipath artifacts which deteriorate the quality of OCT imaging. We demonstrate that a w-type DCF, characterized by a depressed cladding layer between the core and the multimode cladding, can eliminate OCT multipath artifacts. The modal contents of the fiber are determined from simulation and verified experimentally. A w-type fiber-based endoscope is used to generate co-registered OCT and autofluorescence imaging (AFI) with reduced artifacts. Results are compared with a DCF-based catheter.
