Optical pulse shaper

摘要

A waveform converter (10) for altering the waveform and optical spectrum of an optical signal comprises a nonlinear element (12) having a nonlinear effect on optical pulses, a dispersion element (14) having a dispersion effect on optical pulses, and a wavelength selecting element (16) configured to select spectral components in a desired wavelength region. In a specific embodiment, a 1550nm band zero-dispersion shifted fiber is used as the nonlinear element, and a 1300nm band zero-dispersion fiber is used as the dispersion element.
