Abstract
A laser device includes a first waveguiding layer, an active layer, a second waveguiding layer, a contact layer, a first insulating layer, a plurality of hole fillings, a first electrode, and a second electrode. The first waveguiding layer, the active layer, the second waveguiding layer, and the contact layer are stacked in sequence to form an epitaxy structure. The epitaxy structure has a first platform, the first platform has multiple holes to form a photonic crystal structure. The first insulating layer is over an upper surface and a sidewall surface of the first platform, wherein the first insulating layer has a first aperture corresponding to the photonic crystal structure. The hole fillings are respectively filled in the holes. The first electrode is over the photonic crystal structure. The second electrode is electrically connected to the first waveguiding layer.
