In this paper, we present the development and performance of a 940nm multimode VCSEL with 3-dB small-signal modulation bandwidth exceeding 25GHz over temperature and relative intensity noise (RIN) below -145dB/Hz, suitable for 100Gb/s per lane data transmission. The first approach is based on the optimization of the VCSEL photon lifetime. The second one introduces a novel design based on oxidizing the apertures from. We report high frequency (20-100 GHz range) optical field intensity oscillations in laterally-coupled-cavity verticalcavity surface-emitting lasers with several different techniques. Such OIs typically operate over a temperature.
