ABSTRACT

This chapter introduces an eigenvalue modulated optical fiber transmission system based on digital coherent technology. It demonstrates the eigenvalue modulated transmission system. The chapter investigates the noise tolerance of the eigenvalues. The nonlinear Schrodinger equation, which describes the behavior of the complex envelope of an electric field propagating in a nonlinear dispersive fiber, can be solved analytically by using the inverse scattering transform. The amplitude of the narrowest pulse is calibrated by multiplying a constant number, by which the pulse has only one discrete eigenvalue. The light sources used at the transmitter and the receiver which is used to generate local oscillating light are semiconductor laser diodes with an external cavity with line widths 1 kHz and 100 kHz.
