Optimization of the parameters of the detector of ionizing radiation on the base of waveguide ring resonators with hyperlinked fluoropolymer

We demonstrated the possibility of using the microring resonators based on the slot waveguide for measuring the absorbed dose of ionizing radiation. In order to increase the sensitivity of the waveguide guiding properties to ionizing radiation effects, the slots are filled with hyperlinked fluoropolymer. The optimization of the parameters of the slot waveguides to achieve the maximum detector sensitivity to the ionizing radiation effect has been carried out. The sensitivity of the detector on the base of double-slot waveguides with optimized parameters and a radius of the waveguide bend equal to 67.8 µm is 103.5 µA/kGy (1.035 µA/krad), the measuring range is 85 kGy (8.5 Mrad), and the detector resolution is 0.2 Gy (20 rad).
