Abstract
A light emitting device including a first mirror layer, a second mirror layer disposed on the first mirror layer, a cavity layer disposed between the first mirror layer and the second mirror layer and configured to generate light, and a mesa exposing side surfaces of the second mirror layer and the cavity layer, in which the second mirror layer includes at least one oxidized layer forming an aperture through which light generated in the cavity layer is configured to pass, and lengths of the oxidized layer from edges of the oxidized layer to the aperture are in the range of 0.95 to 1.05 times a diameter of the aperture.
Claims20
A light emitting device comprising:
- a first mirror layer;
- a second mirror layer disposed on the first mirror layer;
- a cavity layer disposed between the first mirror layer and the second mirror layer and configured to generate light;
- and
- a mesa exposing side surfaces of the second mirror layer and the cavity layer,
- wherein the second mirror layer comprises at least one oxidized layer forming an aperture through which light generated in the cavity layer is configured to pass, and
- wherein lengths of the oxidized layer from edges of the oxidized layer to the aperture are in the range of 0.95 to 1.05 times a diameter of the aperture.
A light emitting device comprising:
- a first mirror layer;
- a second mirror layer disposed on the first mirror layer;
- a cavity layer disposed between the first mirror layer and the second mirror layer and configured to generate light;
- a mesa exposing side surfaces of the second mirror layer and the cavity layer,
- a first pad region electrically connected to the first mirror layer;
- and
- a second pad region at least partially disposed on the mesa and electrically connected to the second mirror layer,
- wherein the second mirror layer comprises at least one oxidized layer forming an aperture through which light generated in the cavity layer is configured to pass,
- wherein the second pad region comprises an open portion exposing an upper region of the mesa, and
- wherein the open portion overlaps the aperture in plan view and has a diameter greater than a diameter of the aperture.
A light emitting device comprising:
- a first mirror layer;
- a second mirror layer disposed on the first mirror layer;
- a cavity layer disposed between the first mirror layer and the second mirror layer and configured to generate light;
- and
- a mesa exposing side surfaces of the second mirror layer and the cavity layer,
- wherein the second mirror layer comprises at least one oxidized layer forming an aperture through which light generated in the cavity layer is configured to pass, and a plurality of first and second refractive index layers repeatedly stacked in sequence on the oxidized layer, and
- wherein a thickness of the oxidized layer is less than a thickness of the first or second refractive index layer.
