Experimental demonstration of the Vernier effect using series-coupled racetrack resonators

We demonstrate the design and performance of series-coupled racetrack resonators in silicon-on-insulator. The device was modeled and optimized by tuning various parameters such as power coupling factors and resonator dimensions. The Vernier effect is experimentally verified with an extended free spectral range of 36.2 nm and an interstitial resonance… CONTINUE READING
