Wavelength Extension of Optical Signals Based on Cascaded Modulation

Wavelength extension of optical signals plays an important role in optical computation and optical signal processing. In this paper, a wavelength extension architecture based on MZM and PM cascade is proposed to realize configurable wavelength extension of optical signals and form optical homologous copies at dozens of different wavelengths. In the simulation, the wavelength extension achieves the extended spectrum with 39 flat beams, the flat beams account for 37.86% of the total beams, and the flatness reaches 1.05dB.
