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. We report high frequency (20-100 GHz range) optical field intensity oscillations in laterally-coupled-cavity verticalcavity surface-emitting lasers with several different techniques. The oscillation frequency is defined by the photon energy splitting of the coupled states. A −3 dB bandwidth greater than 35 GHz and a RIN of less than −152 dB/Hz are demonstrated. The state of the art of present designs of VCSELs is summarized, includin...
