(color online) Surface temperature (a) and details distribution on active layer (b) for optimized VCSEL array. The maximum temperature of the device is 356.1709 K. em1, em2, ms1, ms2 have the same meanings as Fig. 2 defined but are in the horizontal direction here and mm means the middle row of mesas.
