Abstract

An asymmetrical H-shaped resonator (ASH) has been designed using gold on a fused silica substrate. The aim is to obtain a high - quality factor at the reflectance resonance peaks in the mid - infrared wavelength of 2 μm to 8 μm. The structures were modelled using the Finite Difference Time Domain (FDTD) Lumerical Solution simulation software by adjusting the parameter of periodic boundary condition on the X and Y-axis and perfectly matched layer (PML) on the Z- axis. The asymmetric structures give double resonance peaks that depend on the arm-length of the structure. The periodicity along the X and Y-axis was varied to tune the width of the resonant peaks in order to obtain the maximum Qfactor. Experimental results broadly confirm the simulations.
