We present results on a dissipative modulation instability caused by the presence of asymmetric spectral losses for signal and idler waves. Such instability can occur without satisfying standard phase-matching conditions and has applications in a variety of nonlinear optical systems especially in the design of a novel class of fiber optics parametric amplifiers, optical parametric oscillators and optical frequency combs sources.
