고속 파장가변 모드잠김 레이저의 제작 및 출력특성

다국어 초록 (Multilingual Abstract)

We demonstrate a wavelength swept mode-locked ring laser for the frequency domain optical coherence tomography(FD OCT). A laser is constructed by using a semiconductor optical amplifier, fiber Fabry-Perot tunable filter and 2.6 ㎞ fiber ring cavity. Mode-locking is implemented by 2.6 ㎞ fiber ring cavity for matching the fundamental or harmonic of cavity roundtrip time to a sweep period. The wavelength sweeps are repetitively generated with the repetition period of 77.2 ㎑ which is the parallel resonance frequency of Fabry-Perot tunable filter for the low driving current consumption of the fiber Fabry-Perot tunable filter. The wavelength tuning range of the laser is more than FWHM of 61 ㎚ centered at the wavelength of 1320 ㎚ and the linewidth of the source is 0.014±0.002 ㎚.
