A laser diode that uses air as a reflective layer, thereby enhancing refractive index difference with respect to an oscillating laser beam, and a method for fabricating such a laser diode are provided. The laser diode includes a substrate, a laser oscillating layer formed on the substrate, an upper electrode formed on the laser oscillating layer, and a reflective layer formed at one side of the laser oscillating layer, wherein the reflective layer comprises air layers. According to the laser diode and the method for fabricating the same, it is possible to form a reflective layer having a higher reflectivity with a reduced number of pairs of reflective layers, thereby making a laser diode whose threshold voltage is reduced and which can produce a high-output laser beam.
