    摘要： The present invention relates to a method of mass fabricating a hyperboloid-drum element which is uniform in size and with the diameter of an active layer (active region or gain medium) ranging from tens of nm to less than a few μm, and to an element fabricated thereby. According to the present invention, the fabrication method of the hyperboloid-drum element comprises forming an epitaxial layer which includes an n-type semiconductor joined with a p-type semiconductor on a substrate and an active region near a border region and a boundary between the n-type semiconductor and the p-type semiconductor; and etching the epitaxial layer into a shape of the hyperboloid-drum having the minimum diameter at the active region by an ion-beam etching method. The hyperboloid-drum element fabricated in accordance with the present invention has advantages of uniformity in size and good reproducibility.

    摘要： A three-dimensional (3D) photonic quantum ring (PQR) laser for a low power consumption display, wherein the PQR laser has a sufficient small radius to adjust an inter-mode spacing (IMS) of oscillation modes discretely multi-wavelength-oscillating in an envelope wavelength range within the gain profile of a given semiconductor material of the PQR laser so that the IMS has a maximal value and the number of the oscillation modes is minimized. The PQR laser exhibits multi-wavelength oscillation characteristics according to a 3D toroidal cavity structure, and is designed to exhibit a threshold current lower than those of LEDs and to have multi-wavelength modes in an envelope wavelength range of several nm to several tens of nm. The PQR laser consumes reduced power while maintaining desired color and high brightness equal to those of the LEDs, through an adjustment of the multi-wavelength oscillation characteristics and IMS of the PQR laser.
