一种高速宽带扫频光源的研究 下载: 1158次
ing at the problem of insufficient sweep range of the swept source used in the existing swept source optical coherence tomography (SS-OCT), a Fourier domain mode-locking(FDML) high-speed broadband swept source based on a quantum dot semiconductor optical amplifier (QD-SOA) and a quantum well semiconductor optical amplifier (QW-SOA) in parallel is studied. The output characteristics of two types of SOA are studied, and the QW-SOA with a center wavelength of 1310 nm and the QD-SOA with a center wavelength of 1280 nm are placed in parallel in the fiber annular cavity. A high-speed broadband swept source is developed combined with FDML. The sweep range is 318 nm, the full width at half maximum is 110 nm, the sweep speed is 101 kHz, the average output optical power is 7.8 mW, and the instantaneous linewidth is less than 0.1 nm, respectively.
