We consider a new type of integrable coupled nonlinear Schrodinger (CNLS)
equations proposed by our self [submitted to Phys. Plasmas (2011)]. The explicit
form of soliton solutions are derived using the Hirota's bilinear method.
We show that the parameters in the CNLS equations only determine the regions
for the existence of bright and dark soliton solutions. Finally, through
the linear stability analysis, the modulational instability condition is given.
