Abstract

The performance of the oxide-confined surface relief (SR) structure vertical-cavity surface-emitting laser (VCSEL) is simulated and analyzed by using the Finite Difference Frequency Domain (FDFD) microcavity model available in the PICS3D simulation package. Using the full vectorial microcavity model enables an accurate analysis of both the dominant and higher order modes, thus more insight into the cavity structural parameters can be investigated. In this proceeding, the impact of the oxide layer and the SR layer on both the emitting laser as well as the far field characteristics is investigated. The simulated Surface Relief (SR) VCSEL shows a threshold current increase to 1.2mA compared to 1.0mA without the SR layer, and far field divergent angles decrease to almost 10°.
