We provide a comprehensive experimental and theoretical study of incoh
erently coupled photorefractive spatial-soliton pairs in all three pos
sible realizations: bright-bright, dark-dark, and dark-bright. We also
show that when the total intensity of two coupled solitons is much lo
wer than the effective dark irradiance, the coupled soliton pair is re
duced to Manakov solitons. In all cases, mutual trapping of both compo
nents in the coupled soliton pair is verified by analyzing, experiment
ally and numerically, the beam evolution after decoupling. (C) 1997 Op
