Abstract: A lens reflecting a light of a predetermined wavelength, or transmitting and condensing or diverging the light is provided. The lens includes a substrate, and a quasi-periodic structure layer. A plane of the quasi-periodic structure layer is divided into unit cells and is filled with the unit cells in a two-dimensional period. The unit cell has a first region and a second region. An occupancy rate is changed as a distance from a center of the substrate. A resonance mode is defined by a relationship between the occupancy rate and the period length. A lowest order resonance mode is defined by the resonance mode. The period length is set to a predetermined value within a predetermined range including an optimum value. Another lens is provided. A minimum occupancy rate is defined by a smallest occupancy rate. A variation range of the occupancy rate changes across the minimum occupancy rate.
