MOVPE-grown GaInNAs VCSELs at 1.3 µm with conventional mirror design approach

A 1.3 μm oxide confined GaInNAs VCSELs designed, using the same design philosophy used for standard 850 nm VCSELs is presented. The VCSELs have doped mirrors, with graded and highly doped interfaces, and are fabricated using production-friendly procedures. Multimode VCSELs (11 μm oxide aperture), with an emission wavelength of 1,287 nm have a threshold current of 3 mA and produce 1 mW of output power at 20 degrees Celsius. The maximum operating temperature is 95 degrees Celsius. Emission at 1,303 nm with 1 mW of output power and a threshold current of 7 mA has been observed from VCSELs, with a larger detuning between the gain peak and the cavity resonance.
