High-speed vertical-cavity surface-emitting lasers of 1550 nm spectral range based on ten compressively strained In(Al)GaAs QWs were fabricated by molecular-beam epitaxy and direct double wafer-fusion technique. The devices  demonstrate threshold current of 2 mA and maximum output optical power of 4.8 mW. The effect of saturable absorber was observed at a temperature above 50 °C. Small signal analysis revealed that modulation bandwidth f-3dB and the resonant frequency fR of 8 GHz and 12 GHz, respectively, can be reached for presented VCSELs design. The NRZ-mode data rate up to 20 Gbps at 20 °C across the distance of 1000 meters was demonstrated.
