Designing of Universal WGM Biosensor from Micro Ring Resonator
The WGM biosensor using a nonlinear silica micro ring resonator coating by nano gold layer is designed and examined. The simulation results of Gaussian laser pulses propagating in the symmetry waveguide shows good behavior of the existence of whispering gallery mode outside the surface of the ring resonators coating by a very thin nano gold layer to trap biomolecules with the plasmonic interaction. The output shifted signals from the designed sensor have an accuracy to characterize types of the specific biomolecules as well.
