C-band swept wavelength erbium-doped fiber laser with a high-Q tunable interior-ridge silicon microring cavity

We demonstrate an erbium-doped fiber laser with a tunable silicon microring cavity. We measured a narrow laser linewidth (16 kHz) and single-mode continuous-wave emission over the C-band (1530nm-to-1560nm) at a swept-wavelength rate of 22,600nm/s or 3106THz/s.
