An optical network comprising a broad band optical source having a temporal characteristic and an optical wavelength conversion apparatus. The optical wavelength conversion apparatus comprising a laser means for producing a narrow band optical spectrum signal, a means for receiving a broad band optical signal having a temporal characteristic, and a spectral compactor means. The spectral compactor means is responsive to the narrow band optical spectrum signal and the broad band optical signal, for modulating the narrow band optical signal with the temporal characteristic of the broad band optical signal. A polarization reset apparatus comprises a laser means for producing a narrow band optical spectrum signal having a first polarization, a means for generating a second optical signal having a temporal characteristic and a second polarization, and a spectral compactor means responsive to the first and second optical signals for modulating the first optical signal with the temporal characteristics of the second optical signal to produce an output signal having the temporal characteristic of the second optical signal and the spectral and polarization characteristics of the first optical signal.
