Abstract
Data patterns are shown to affect the far field distribution of vertical cavity surface emitting lasers (VCSELs). Two data patterns with different frequency content resulted in different beam profile distributions even though both patterns had 50% duty cycles resulting in the same thermal dissipation. The effect of gain switching and varying high and low drive levels was also investigated. Angle dependent waveforms displayed overshoot on axis and undershoot off axis. The potential impact of pattern dependent launch conditions is discussed.
