Wavelength-flattened directional coupler based mid-infrared chemical sensor using bragg wavelength in subwavelength grating structure

Wavelength-flattened directional coupler based mid-infrared chemical sensor using bragg wavelength in subwavelength grating structure

In this paper, we report a compact wavelength-flattened directional coupler (WFDC) based chemical sensor featuring an incorporated subwavelength grating (SWG) structure for the mid-infrared (MIR). By incorporating a SWG structure into directional coupler (DC), the dispersion in DC can be engineered...
