Abstract :
Interferometric noise due to crosspoint crosstalk in optical WDM and TDM switching fabrics is substantially reduced by manipulation in the time and/or wavelength domains. Furthermore, providing sufficient discrete wavelengths are available, or sufficient time compression can be realized, almost all noise may be eliminated at the expense of additional equipment. Practical realizations of the proposed scheme are discussed.<>
