Abstract :
We present a new approach for InP-based long-wavelength VCSELs based on buried tunnel junctions. Excellent cw laser performance has been demonstrated for the 1.45-1.85 μm wavelength range, such as sub-mA threshold currents, 0.9 V threshold voltage (at λ=1.55 μm), 30-100 Ω series resistance, differential efficiencies >25%, 90°C cw operation, stable polarization and single-mode operation with SSR of the order 50 dB
