Paper Abstract

The superstructured-grating distributed-Bragg-reflector laser is a small (shorter than 1 mm in length) and relatively cheap swept source for optical-frequency-domain- reflectometry optical coherence tomography (OFDR-OCT), which practically enables use of multiple sources in a single OCT system. Simultaneous scanning of multiple sources over different wavelength regions and at different wavelength values in the same wavelength region enable improvement of the resolution and scanning speed, respectively. Those improvements have been demonstrated using C-band and L-band SSG-DBR sources.
