摘要
Photonic devices may include a first ring resonator and a second ring resonator located within the first ring resonator, the second ring resonator separated from and optically coupled to the first ring resonator. A waveguide structure is optically coupled to the first ring resonator and may be parallel bus waveguides optically coupled on opposite ends of the first ring resonator or a u-shaped waveguide wrapped substantially around the first ring resonator. A third ring resonator may located within the second ring resonator and may be separated from and optically coupled to the first ring resonator and the second ring resonator. A sensing medium may be disposed within the interior of the third ring resonator and optically coupled to the third ring resonator. The sensing medium is configured to undergo a change in refractive index responsive to one or more analytes bound to the sensing medium.
