Spectral and temporal evidence of robust photonic bound states in the continuum on terahertz metasurfaces
In collaboration with the group of Sanchez Gil (CSIC-Spain), we have demonstrated that a simple array of gold dimers can support modes with infinite life-times. We have investigated these, so-called, Bound States in the Continuum using THz time-domain spectroscopy. Read more in our published Optica.
