Abstract: A spectrometer system is described. The system comprises a signal input port and a pump input port, respective signal and pump dispersion fibers, a nonlinear optical fiber section, and an output dispersion fiber. The dispersion fibers are configured to apply predetermined spectral dispersion on light input associated with signal and pump inputs. The nonlinear optical fiber section is configured to receive dispersed signal and pump waves and enable nonlinear interaction between the signal and pump waves. The output dispersion fiber is configured to receive light resulting from said nonlinear interaction and apply predetermined dispersion to the received light, thereby providing output light having mapping between time and spectral components of the input signal. Wherein at least one of the signal input port and pump input port comprises temporal speckle generating unit configured to affect optical pulses passing through to induce temporal speckles within said optical pulses.
