Abstract
We report a novel (to the best of our knowledge) simultaneous two-wavelength band swept laser source and dual-band common-path swept-source optical coherence tomography (SS-OCT). Synchronized dual- wavelength tuning is performed by using two laser cavities and narrowband wavelength filters with a single dual-window polygonal scanner. Measured average output powers of 60 and have been achieved for the 1310 and bands, respectively, while the two wavelengths were swept simultaneously from 1227 to for the band and from 1519 to for the band at an A-scan rate of . Broadband wavelength-division multiplexing is used for coupling two wavelengths into a common-path single-mode GRIN-lensed fiber probe to form dual-band common-path SS-OCT. Simultaneous OCT imaging at 1310 and is achieved. This technique allows for in vivo high-speed OCT imaging with potential application in functional (spectroscopic) investigations.
