Chromatic Dispersion Induced Second-Order Distortion in Long-Haul Photonic Links

Closed form expressions for the theoretical photocurrent of a photonic link with a dispersive fiber are derived for multiple external modulation schemes. These expressions are used to derive the link's output power at both the fundamental and second-order frequencies. Expressions for phase modu...

Summary:Closed form expressions for the theoretical photocurrent of a photonic link with a dispersive fiber are derived for multiple external modulation schemes. These expressions are used to derive the link's output power at both the fundamental and second-order frequencies. Expressions for phase modulation (with and without an asymmetric Mach-Zehnder Interferometer), and both X- and Z-cut LiNO3 intensity modulation are presented and compared.
