Y junction semiconductor laser arrays have attracted attention because they tend to favor in-phase operation and therefore generate predominantly single lobe output beams [1,2]. Recent streak camera measurements, however, have indicated that these lasers exhibit sustained self-pulsations under CW pumping [4]. These pulsations have not yet been properly explained. In this paper we use a propagation model to examine the spatio-temporal dynamics of Y junction lasers and arrays. We find that even a… CONTINUE READING
