    Abstract: PROBLEM TO BE SOLVED: To provide devices and methods that enable stable, low-noise, and efficient operation of a swept-source OCT (SS-OCT) system at high speed, with continuous real-time image display.SOLUTION: A semiconductor optical amplifier (SOA) in a laser ring is chosen to provide low polarization-dependent gain (PDG), and a booster semiconductor optical amplifier outside the optical ring is chosen to provide high polarization-dependent gain. The use of a semiconductor optical amplifier with low polarization-dependent gain nearly eliminates variations in the polarization state of the light at the output of the laser, but does not eliminate the intra-sweep variations in the polarization state at the output of the laser, which can degrade the performance of the SS-OCT system.
