Photonic ring resonance is a property of light where in certain circumstances specific
wavelengths are trapped in a ring resonator. Sensors based on silicon photonic ring
resonators function by detecting the interaction between light circulating inside the sensor
and matter deposited on the sensor surface. Binding of biological material results in a
localized change in refractive index on the sensor surface, which affects the circulating
optical field extending beyond the sensor boundary. That is, the resonant wavelength will …
