Abstract: A resonant cavity structure includes an upper layer in which first dielectric layers and second dielectric layers having different refractive indices are alternately stacked, a lower layer in which the first dielectric layers and the second dielectric layers are alternately stacked, and a cavity formed between the upper layer and the lower layer, wherein the cavity includes a wavelength conversion material that absorbs light having a first wavelength and emits light having a second wavelength different from the first wavelength, the resonant cavity structure is designed so that resonance occurs in the cavity at the first wavelength, and is provided so that an excitation light of the first wavelength is incident from below the lower layer.
