Abstract: Long-wavelength vertical cavity surface emitting lasers (VCSELs) operating in the 1.3 µm to 1.5 µm wavelength range are considered the best candidate for the future low-cost reliable light sources in fiber communications. However, the room temperature performance of GaInAsP/InP long-wavelength InP lattice matched material system falls below the shortwavelength VCSELs. In this work we present the results of our studies concerning I-V and electroluminescence measurements on GaInAsP/InP structure with distributed Bragg reflectors. The device lased at 0.98 µm at room temperature.
