WebApr 14, 2024 · In quantum mechanics, a bound state is a state whose energy is lower than that of a continuum state, where an electron is bound around the nucleus. The energy of the BIC mode is also lower than that of the continuum state, but the photon in this state is not bound in the medium. Rather, it is restricted near the surface of the medium.
