Abstract
Methods of manufacturing a lasing device are provided by some embodiments, the methods including: creating a silicon micro ring with a predetermined radius and a predetermined first cross-sectional dimension; creating a silicon waveguide with a predetermined second cross-sectional dimension, the silicon waveguide spaced from the silicon micro ring by a predetermined distance; and wherein the predetermined distance, the predetermined radius, the predetermined first cross-sectional dimension, and the predetermined second cross-sectional dimension are determined so that at least one first whispering gallery mode resonant frequency of the silicon micro ring and at least one second whispering gallery mode resonant frequency of the silicon micro ring are separated by an optical phonon frequency of silicon.
