Abstract
This paper has investigated the thickness effects on sub-wavelength (period <λ) Lamellar grating waveguide sensors with TE polarization incidence. Also, the thickness effects of Lamellar grating and its influence on the sensor sensitivity are studied. Simulation results reveal that as the thickness of Lamellar grating is increased, the more resonance modes will be induced as well. However, it is difficult to recognize the peak shift of the fundamental mode while the thickness of grating is different and the thickness of waveguide is the same.
