In a laser source, a first optical waveguide includes a gain medium, and a second optical waveguide includes a phase tuner which adjusts a phase value of the phase tuner to specify the wavelength of the laser source. Furthermore, the laser source includes a first ring resonator and a second ring resonator, which, respectively, are optically coupled to the first optical waveguide and the second optical waveguide at opposite ends of the laser source. In particular, coupling wavelengths of the first and second ring resonators may match a wavelength of the optical signal, thereby defining an optical resonance cavity in the laser source and selecting a laser mode of the laser source which is associated with the wavelength. Additionally, the laser source includes an optical amplifier that receives and amplifies the optical signal output from the optical resonance cavity. |
