Directional Coupler Biosensor Based on Thermooptic Detection Mechanism in Silica Waveguide
We propose a directional coupler (DC) biosensor to detect the concentration of glucose based on the thermooptic detection mechanism in silica waveguide. We discuss the design principles using the coupled-mode theory of DC and deduce the conditions for a valid biosensor model. The coupling length, th...
