Investigation of Grating-Assisted Trimodal Interferometer Biosensors Based on a Polymer Platform
A grating-assisted trimodal interferometer biosensor is proposed and numerically analyzed. A long period grating coupler, for adjusting the power between the fundamental mode and the second higher order mode, is investigated, and is shown to act as a conventional directional coupler for adjusting th...
