Paper Abstract

In this paper, we present the design and manufacturing of photonic-crystal long-wavelength VCSELs. They were developed to provide a high-performance low-cost alternative to Fabry-Perot and DFB lasers for 2.5 Gbps applications within the intermediate range access network. The paper covers photonic-crystal long-wavelength device design, manufacturing process, DC and AC characteristics, as well as reliability studies. The addition of photonic-crystal structures to the long-wavelength vertical-cavity surface-emitting lasers allows us to increase the oxide diameter. This reduces the series resistance as well as the thermal resistance resulting in increased single-mode output-power and an enhanced high-temperature performance of our devices.
