Here we present an abnormal phenomenon we call “resonance-forbidden second-harmonic generation” in a nonlinear photonic crystal slab. We show that the second harmonic fields of certain modes supported by the structure can be completely non-radiative. As a result, no pumping energy is transferred into the second harmonic frequency and the second harmonic generation is completely suppressed. We identify two mechanisms that can achieve this phenomenon: symmetry protection and parameter tuning through numerical simulation.
