Abstract:The electromagnetic field enhancement caused by high Q factor resonance can greatly contribute to the magneto-optical Kerr effect of nanophotonic devices. Here we propose a magneto-optical metasurface supporting quasi bound states in the continuum (quasi-BIC) and theoretically investigate the evolution process from BIC to quasi-BIC. By applying external magnetic field, the BIC in our proposed metasurface can transform into quasi-BIC with finite Q factor up to 33620. Meanwhile, the polarization singularity of t… Show more
