- Abstract :
A polarization-insensitive monolithic 40 Gbps SOA-MZI wavelength converter has been developed. Based on the photon-electron
rate equation, we optimized the dimentions of the waveguide structure to maximize the field confinement in the active layer.
An InGaAsP active layer with narrow SOA waveguide effectively enables polarization-insensitive high-speed wavelength conversion.
High-precision wafer processing technique enabled the fabrication of sub-micron-wide active waveguides with low current leakage.
Input waveguide arrays were fabricated at intervals of 25 m and mounted in a module with two-lens aspherical lens optics.
The 40 Gbps-NRZ wavelength conversion experiment demonstrates a clear eye opening over full C-band operation.
