Embodiment Construction
[0017] In order to better understand the technical solution of the present invention, the implementation manner will be further described below in conjunction with the accompanying drawings.
[0018] figure 1 It is a schematic structural diagram of the MZI-SOA wavelength converter in the present invention. The MZI-SOA wavelength converter is composed of two SOAs that constitute a Mach-Zehnder interference structure (MZI). It has a continuous optical input port, an output port, and two signal optical input ports. The signal light can be from any signal light Input port input.
[0019] Continuous light λ c Entering the MZI-SOA wavelength converter, it is first divided into two beams. When the two beams propagate in the SOA, the effective refractive index of the SOA changes with the change of the optical power injected from the signal light input end, resulting in continuous light λ c The phase shift in the SOA changes. Through the MZI interference structure, the phase shift c...
