Abstract

We investigate optically pumped lasing of GaInNAs-based VCSELs emitting at 1.3 mum. The samples measured were full device structures including doping. Conventional p-i-n-type VCSELs showed high internal threshold excitation densities of around 10 MW/cm(2). Improvements, especially the introduction of a tunnel junction reduced the threshold to about 128 kW/cm(2) and should after further optimization enable us to realize an electrically pumped 1.3 mum VCSEL in the near future.
