A photonic crystal surface-emitting laser includes a light emitting module and a driving module. The light emitting module includes a photonic crystal layer, an active light emitting layer on a side of the photonic crystal layer, a first electrode on a side of the active light emitting layer facing away from the photonic crystal layer, and a second electrode partially on the side of the active light emitting layer facing away from the photonic crystal layer. The driving module makes electrical contact with surfaces of the first electrode and the second electrode facing away from the photonic crystal layer. The driving module outputs driving signals to the first electrode and the second electrode to drive the active light emitting layer to generate photons. The photons are incident into the photonic crystal layer to generate a laser light through oscillation on Bragg diffraction. An optical system is also disclosed.
