We review the recent progress of information theory in optical communications, and describe
the current experimental results and associated advances in various individual technologies …

Fiber-optic communication systems have revolutionized our telecommunication
infrastructures–currently, almost all telephone land-line, cellular, and internet …

Information-theoretic limits to spectral efficiency in dense wavelength-division-multiplexed
(DWDM) transmission systems are reviewed, considering various modulation techniques …

The problem of analytical evaluation of the maximum rate at which information can be
reliably transmitted on a nonlinear wavelength division multiplexing fiber-optic channel with …

We study the statistics of optical data transmission in a noisy nonlinear fiber channel with a
weak dispersion management and zero average dispersion. Applying analytical …

Since its early commercial deployment in the late 1980s, optical fiber has evolved to become
the predominant carrier of the globe's communications. Yet, after accommodating the world's …

Two-dimensional (2-D) codes for optical CDMA (OCDMA) are increasingly important
because the code set size (cardinality) of such codes is large and the codes have good …

There have been numerous attempts to determine the channel capacity of a nonlinear fiber-
optic communication channel. The main approach was to consider amplified spontaneous …

We give a necessary and sufficient condition for a function $ E (t) $ being of minimum phase,
and hence for its phase being univocally determined by its intensity $| E (t)|^ 2$. This …

The capacity of the channel defined by the stochastic nonlinear Schrödinger equation, which
includes the effects of the Kerr nonlinearity and amplified spontaneous emission noise, is …
