$A Highly Sensitive Refractometric Sensor Based on Cascaded SiN Microring Resonators$

A Highly Sensitive Refractometric Sensor Based on Cascaded SiN Microring Resonators

We investigate a highly sensitive optical sensor based on two cascaded microring resonators exploiting the Vernier effect. The architecture consists of two microrings with a slight difference in their free spectral ranges. This allows the generation of the Vernier effect for achieving ultra-high sen...
