Design of the Bimodal Grating Sensor with a Built-In Mode Demultiplexer
This new sensor design provides good volume sensitivity (around 1600 nm/RIU) via collinear diffraction by the asymmetric grating placed in the waveguide vicinity. It provides the mode transformation between the fundamental TE<sub>0</sub> and the first TE<sub>1</sub> modes of...
