A new MOCVD InP/AlGaInAs distributed Bragg reflector for long-wavelength VCSELs is presented. The InP/AlGaInAs system presents a high potential for 1.55 µm VCSELs owing to the combination of its high refractive index contrast (Δn ≃ 0.34) and its low conduction band discontinuity (ΔEc ≃ 150 meV). InP/AlGaInAs mirrors and one half VCSEL (bottom mirror and λ cavity) have been fabricated for the first time using AlGaInAs transparent to 1.55 µm.
