Abstract :
In this work, AlGaAs-GaAs semiconductor vertical-cavity surface-emitting laser (VCSELs) with incorporation of two-dimensional photonic crystal (PC) waveguides into their top distributed Bragg reflector are experimentally and theoretically investigated. This is done to control the transverse optical modes in the cavity and is also seen to improve the modulation characteristics. Results for VCSELs with PC are compared to VCSELs without the PC and with VCSELs with micropillar microcavities.
