A single oscillation-mode laser employing the asymmetric waveguide structure is designed and analyzed. The mode selection mechanism is realized by using an asymmetric Bragg reflection waveguide (BRW) and shown to be effective to achieve high side-mode suppression ratio (SMSR). As an example, a silicon-based quasi-one-dimensional BRW with Er-doped Si-nanocrystal in the silicon oxide core is considered and illustrated for the laser structure. Guidance properties and threshold conditions are examined to verify the design procedure and performance feasibility for the single oscillation mode laser.
