“…Among the few demonstrations, there are two single-longitudinal-mode (SLM) erbium-doped fiber lasers incorporating a silicon-on-insulator (SOI) micro-ring resonator (MMR) as optical filter that were demonstrated. In the first case, the SLM was achieved by employing a saturable absorber [19] while it was achieved by employing a compound-ring architecture [20] in the other case. In both cases, a SOI MMR was used as fixed grid filter, and the lasing wavelength selectivity was obtained by controlling the birefringent loss with a polarization controller.…”

Agile optical systems and elastic optical networks demand for flexible, high-performance laser sources. We demonstrate a hybrid silicon-fiber laser that can be largely tuned in wavelength, switched in frequency spacing and easily switched between multi-and single-wavelength operations. Single-mode laser with a fiber-coupled output power of 6 to 8 dBm was measured across the spectral range of 1545 nm to 1560 nm. No significant sign of power limitation from nonlinear absorption or free carrier generation in silicon was found. It is thus expected that a higher output can be obtained by improving the gain saturation performances as well as the fiber-to-chip coupling efficiency. For multi-wavelength operation, we have achieved a frequency spacing switchable between 56 GHz, 75 GHz, and 225 GHz. For both the multi-and single-wavelength operations, a linewidth of less than 20 kHz was measured. All the tuning mechanisms have been realized on the silicon chip, providing a scalable solution for tunable fiber lasers with minimized cost and integration complexity.
