We have demonstrated fully-epitaxial, room-temperature, electrically-pumped VCSELs based on III-As compounds with low threshold current density, very high differential efficiency and low threshold voltage by employing multiple-active-regions in a single cavity. Even higher differential efficiencies should be possible with optimized cavity designs. The high differential efficiency and high output powers makes these VCSELs good candidates for low-noise, high-efficiency microwave links. Also, when integrated with a series connected detector, analog repeaters, amplifying wavelength converters, and lossless signal tapping are possible.
