“…0268-1242/12/094007+06$33.00 are natural and coprime numbers [8]. The tuning enhancement factor of the coupled ring is equal to the natural number (N peak of ring 1), where the tuning enhancement factor (F) can be defined as…”

“…At the resonance, the 33rd peak of ring 1 will coincide with the 32nd peak of ring 2 and all other peaks will be suppressed. The wavelength tuning range ( λ tune ) is defined as [8]. The wavelength tuning range can be increased by increasing the radius of ring 2, and 155 nm tuning range was estimated for DRQCL design.…”
