摘要： A multiple wavelength surface-emitting laser device equipped with a substrate and a plurality of surface-emitting lasers formed on the substrate by a continuous manufacturing process is provided. Each surface-emitting laser includes a bottom reflection layer on the substrate, that is doped with impurities of one type and composed of alternating semiconductor material layers having different refractive indexes; an active layer that is formed on the bottom reflection layer; an intermediate layer that is doped with impurities of the other type on the active layer; a top electrode that is formed on the intermediate layer to have a window through which light is emitted; and a dielectric reflection layer where dielectric materials with different refractive indexes are alternately layered on the intermediate layer and/or the top electrode to a thickness suitable for a desired resonance wavelength, and the resonance wavelength is controlled by adjusting the thickness of the dielectric reflection layer.

摘要： An apparatus and method for forming an aperture of a vertical cavity surface emitting laser (VCSEL) by selective oxidation, in which resonance peak variations during the formation of the aperture can be measured using an optical spectrum analyzer, so that the size of the aperture can be precisely adjusted. The aperture forming apparatus includes: a furnace having a first window and a second window for transmitting light, and a stage for supporting a wafer for the VCSEL with a pre-oxide layer where an aperture is to be formed; a light source placed outside the furnace, for emitting light through the first window onto the top of the wafer seated on the stage; and an optical spectrum analyzer for detecting the light intensity by receiving light reflecting from the top of the wafer for the VCSEL and passing through the second window.
