We propose and demonstrate the lateral integration of a VCSEL and a slow-light VCSEL amplifier with in-plane resonant wavelength detuning design, enabling the unidirectional coupling and stable single-mode operation with good beam quality. The modelling and simulation result of the wavelength detuning and unidirectional coupling is shown. A slow light laterally coupled from the VCSEL to the amplifier can be amplified uniformly when the amplifier is pumped above the threshold current. We also present the experimental data of the beam quality, output power and spectrum. The measured data show the increased single-mode output power with good beam quality in comparison with conventional VCSELs. A record single-mode power (40 mW) with narrow beam divergence (<0.06°) is presented.

This is the first report on room temperature CW operation of GaAlAs/GaAs vertical Fabry-Perot cavity surface emitting lasers. A vertical microcavity was formed with a diameter of 7 µm and cavity length of 5.5 µm by a two-step MOCVD growth and fully monolithic technology. The threshold current was 32 mA under CW condition at 22.5. Stable single transverse and longitudinal mode operation was obtained.
