An electrically pumped photonic-crystal surface-emitting laser, the epitaxy structure has a first mesa, the first mesa has multiple air holes and forming a photonic crystal structure, the epitaxy structure further has a second mesa, the second mesa and photonic crystal structure is facing the same direction; a first metal electrode arranged on the insulating layer, and covering the photonic crystal structure; a second metal electrode arranged on the second mesa and protruding out of the groove, making the first metal electrode and the second metal electrode face the same direction; and further make the first metal electrode connect to the first connecting metal and make the second metal electrode connect to the second connecting metal for making the photonic crystal structure become flip chip.
