Conditions for the injection locking of vertical-cavity laser arrays are co
nsidered. The injection power required for locking to be achieved depends o
n various parameters such as the injected-field distribution and frequency
as well as the array geometry and pumping strength. The circulating field d
istribution, driven by the injected field, is controlled mainly by the freq
uency detuning from the laser resonances as well as by the injected-field d
istribution. (C) 1999 Optical Society of America. [S0740-3224(99)00401-4].
