Abstract

The fabricated VCSELs with anti-resonant top DBRs exhibit complete single-mode operation up to 3 mW output power even for large oxide aperture diameters up to 11 μm. The far-field can be described well by the Airy function and the corresponding FWHM angle remains below 5.5° with a variation of only 20% from threshold to roll-over. The combination of completely single-mode operation, low series resistance and a very stable low far-field angle make this type of device the emitter of choice for high-speed data transmission.
