Thermal Resonant Response of a Double Subwavelength Gratings in the PT-symmetry Mode

In this paper we numerically investigated the resonance optical response of the double waveguide gratings for green wavelength taking account the thermal effects. It was shown the thermo-optics effect has the main contribution for changing resonance wavelength and width of resonance spectral linewas estimated. The resonance response for passive and PT-symmetry modes. Obtaining results allow using such structure for temperature sensitive sensor applications.
