Abstract
In this paper we present the first InP-based short-cavity Vertical-Cavity Surface-Emitting Laser with an AlGaInAsP/GaInAsP active region and a re-grown and structured GaAs0.51Sb:C/Ga0.47InAs:Si buried tunnel junction (BTJ), which serves as current aperture, grown by LP-MOVPE. We achieved over 1mW single-mode continuous-wave (cw) emission at around 1.3μm wavelength and room-temperature. The small-signal modulation bandwidth exceeds 7.5GHz, which is appropriate for 10Gb/s data transmission, and the series resistance is as low as 24Ω. The latter value indicates around three times lower dissipated power consumption than comparable MOVPE grown InP-based VCSELs.
