Paper Abstract

We demonstrate a wavelength-swept fiber laser based on the dispersion tuning method using a chirped fiber Bragg grating (CFBG) and a reflective semiconductor optical amplifier (RSOA). The laser cavity length is reduced to as short as 2m owing to the short and highly-dispersive CFBG, which is much shorter than the one using dispersion compensating fiber (DCF). The short cavity enables higher sweep speed. We successfully obtain the OCT images of a rolled adhesive tape at the sweep rate of 50kHz.
