Abstract

We propose and demonstrate a wide-bandwidth unidirectional ring cavity wavelength-swept laser using a polygonal scanning wavelength filter and two semiconductor optical amplifiers (SOAs). The center wavelengths of the gain media of the two SOAs are 1020 nm and 1140 nm, respectively. At a scanning speed of 1.8 kHz of the WSL, a wide scanning band of about 223 nm with a 10-dB bandwidth from 959 nm to 1182 nm and an average optical power of 58.28 mW were obtained. It can be used as a broadband optical source for dynamic optical fiber sensor or optical coherence tomography.
