Mirror reflectivity and doping considerations for high-performance oxide-confined vertical-cavity lasers
A systematic study has been carried out on the effects of doping concentration and reflectivity of the mirror and the oxidation fabrication on the efficiency of 850- and 780-nm oxide-confined VCELs. By optimizing the mirror-doping profile and reflectivity, hex > 40-50% have been achieved. Furthermore, the oxidation temperature can directly influence the VCFL performance. Finally, additional optimization studies and the implementation of the results in optimal VCFL structures have been described.
