850-nm vertical-cavity laser diodes with copper-plated heat sinks were fabricated and tested. Vertical-cavity surface-emitting lasers with 10μm aperture diameter and 4μm of electroplated copper demonstrated a maximum −3dB modulation bandwidth of more than 16GHz and a resonance frequency of more than 11GHz at bias current of only 5.4mA,(More)
An error-function analytical expression describing compositional grading in a 850 nm AlGaAs/GaAs top-emitting oxide confined vertical cavity surface emitting laser has been derived. Results are presented showing that the optical properties of the considered device utilizing the proposed error-function compositional scheme are superior over other grading(More)
