Abstract :

Generation of dual-wavelength fiber lasers (DWFLs) has attracted many research interests recently. We demonstrate a stable tunable dual-wavelength erbium-doped fiber laser generated by launching mode-locked laser into an add-drop microring resonator. Two silicon-based high index contrast microring resonators with Q-factors of 1.2 ├?┬?105 and 0.6 ├?┬?105 have been used as adddrop filters independently. The two silicon oxynitride (SiOxNy) microring resonators have different diameters and used as narrow band filter for the generation of stable tunable dual-wavelength lasers with variable free spectral range (FSR) accordingly. As a result, multi-wavelength generation was achieved and demonstrated both theoretically and experimentally with free spectral range (FSR) of 0.202 and 0.404 nm corresponding to the microrings├ó┬?┬? diameter of D=2.54 and D=1.27 mm. A high resolution tunable band pass filter (TBPF) and FBG are then used to filter out switchable and tunable dual-wavelength signals. The dual-wavelength fiber laser (DWFL) with different FSR from 0.404 to 3.232 nm as an integer coefficient of minimum obtained FSR presents. The resulting dualwavelength output had a side-mode suppression ratio (SMSR) of more than 30 dB. Therefore, the microring resonator can be readily integrated into a photonics integrated chip (PIC) for multifunctional applications as the achieved FSR is in linear relation with the ring resonators├ó┬?┬? diameter.
