Abstract
A photonic crystal surface-emitting laser device includes a substrate, a light emitting layer located on a surface of the substrate, a photonic crystal layer located on a side of the light emitting layer facing away from the substrate, and a metasurface located on a side of the substrate facing away from the photonic crystal layer. The light emitting layer is configured to generate photons. The photons incident into the photonic crystal layer generate laser light through a Bragg diffraction oscillation. The metasurface includes a base and a plurality of pillars arranged on a surface of the base at intervals, at least two of the plurality of pillars have different shapes and/or different sizes. The metasurface is configured to receiving the laser light, diffracting the laser light and then emitting the laser light. An optical system having the photonic crystal surface-emitting laser device is also provided.
