We extend the time-domain ptychographic iterative engine to generalized spectral phase-only transfer functions. The modified algorithm, i2PIE, is described and its robustness is demonstrated by different numeric simulations. The concept is experimentally verified by reconstruction of a complex supercontinuum pulse from an all normal dispersion fiber.
