The grating slot waveguide is designed and numerically simulated to obtain a narrow resonant band at a stop-band of the transmission spectra for a realization of a refractive index sensor. The sensing principle has depended on a detection of the shift in the resonant band for a change in the refractive index of a biomaterial. The Q factor of the resonant peak is found out to be 21637. The theoretical...
In this article Bragg grating waveguide with phase shift cavity biosensor is proposed for diagnosis of a various blood components. Analysis is performed for blood plasma, hemoglobin, blood glucose, biotin streptavidin and bovine serum albumin. Detection is done by observing shift in resonant wavelength due to the alteration in refractive index of different components of blood. Finite difference method...
