Transmission resonances in silicon subwavelength grating slot waveguide with functional host material for sensing applications

S. Hadi Badri

A highly sensitive and selective CO2 gas sensor is presented based on a subwavelength grating (SWG) slot waveguide. Polyhexamethylene biguanide (PHMB) as a functional material fill…
