Abstract

We have investigated the potential of asymmetric current injection for polarisation switching in GaAs-based intra-cavity contacted vertical cavity surface emitting lasers using two sets of p- and n-type contacts per device. When using the contacts set along the [110 ] axis, the polarisation was set along [011] while using the contacts along [011] the polarisation switches from the direction along [011] to a direction making an angle of 25 to 90° towards [011].
