Abstract

Metasurfaces possess vast potential for flexible beam shaping with reduced physical footprint compared to traditional refractive bulk optics. Such devices have the potential to revolutionize catheter-based biomedical imaging modalities such as optical coherence tomography (OCT) by enabling smaller catheter designs with enhanced performance and functionality compared to traditional ball lens or GRIN based designs. Previously our group demonstrated the first-ever integration of a metalens into a fully functioning OCT catheter. Here we present the continuation of that work, discussing refinements in both design and fabrication, and our overall efforts to develop metalens catheters as a complete replacement for traditional design.
