The accurate NOR logical operation is completed by properly modulating the target resonant absorption peak (AP) by the external magnetic field and using the peak to ascertain the logical operation. Given the high-quality factor of the resulting APs, the proposed structure can be used to detect four important physical quantities, which are angle, magnetic field, the thickness of ferrite₁, and refractive index (RI). YIG is a typical representative of ferrite. Due to the magneto-optical effect, the PT-symmetry is broken, resulting in a nonreciprocal phenomenon, thereby further realizing NOR logic operation and multi-physical quantity detection on the front and rear scales. Since the RI of YIG is modulated by the magnetic field, the change of the magnetic field can cause the AP generated by the resonance to shift, so that the magnetic field can be detected.</p> 2026-09-30T11:40:56Z Text Journal contribution 10.6084/m9.figshare.34031930.v1 https://figshare.com/articles/journal_contribution/A_multifunctional_layered_photonic_structure_with_NOR_logical_operation_and_multiscale_detection_based_on_the_PT-symmetry_breaking/34031930 CC BY 4.0
