Standard GaAs-based VCSEL structures with doped DBR mirrors are processed into intra-cavity contacted VCSELs with asymmetric current injection to investigate their polarisation behaviour. The processing requires reflectometry measurements during etching of the first and second mesa. The p- and n-contacts are deposited on an AlGaAs layer with the lowest Al-content of the upper and bottom DBR respectively. A dichromate solution was used to etch selectively the higher Al-content layer of the DBRs before depositing the contacts.
