Abstract

We investigate the effect of 2 MeV proton radiation on high-speed oxide-confined vertical cavity surface emitting lasers. Fluences in the range of Φ = 2.5 × 10¹² p/cm² to Φ = 5 × 10¹⁴ p/cm² were studied and laser threshold current was found to degrade linearly with fluence according to a damage factor of K _I = 2.77 × 10^-15cm²/p. Laser operating wavelength increased with fluence and experienced a maximum Δλ/λ of ∼ 0.71% at Φ = 5×10₁₄ p/cm₂. Leakage current also increases as a result of the proton irradiation. We propose a degradation model based on mobility reduction and carrier removal.
