In this paper, we present a novel concept for a multi-channel swept sourceoptical coherence tomography (OCT) system based on photonic integrated circuits(PICs). At the core of this concept is a low-loss polarization dependent pathrouting approach allowing for lower excess loss compared to previously shownPIC-based OCT systems, facilitating a parallelization of measurement units. Asa proof of concept for the low-loss path routing, a silicon nitride PIC-basedsingle-channel swept source OCT system operating at 840 nm was implemented andused to acquire in-vivo tomograms of a human retina. The fabrication of the PICwas done via CMOS-compatible plasma-enhanced chemical vapor deposition to allowfuture monolithic co-integration with photodiodes and read-out electronics. Aperformance analysis using the results of the implemented photonic buildingblocks shows a potential tenfold increase of the acquisition speed for amulti-channel system compared to an ideal lossless single-channel system withthe same signal-to-noise ratio.
