Abstract: A structure of Vertical Cavity Surface-Emitting Laser (VCSEL) comprises an ion-implanted region with gas-furnace configuration arranged in the second mirror layer around a laser light output window, in order to retain several conductive passages between the inner and outer rims of the ion-implanted region, so as to let the aperture of the inner rim of the metal layer (that is, the aperture of the output window) be expanded without loss of resistance. Not only the shading effect can be removed, the spectrum width suppression function can be preserved, but also various photoelectric characteristics such as transmission eye diagram and photoelectric curve linearity can be improved, in addition, high-speed transmission characteristics can also be optimized.
