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(0) and the first TE(1) modes of the silicon wire (0.22 μm by a 0.580 μm cr...
