Abstract :
We propose an index tuned silicon photonic sensor capable of measuring refractive indices of liquid analytes. This sensor uses two microring resonators in cascaded configuration. Conventional double microring resonators display high sensitivity but limited range of detection. We show that the range of detection can be enhanced by more than an order of magnitude by using index tuning.
