Publisher Summary This chapter provides a taxonomy of optical modulation formats along
with experimental techniques for realizing them. High-speed optical transmission systems …

Advanced optical modulation formats have become a key ingredient to the design of modern
wavelength-division-multiplexed (WDM) optically routed networks. In this paper, we review …

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 …

In this paper, we propose and experimentally demonstrate a radio frequency (RF)-tone-
assisted optical orthogonal frequency-division multiplexing (OFDM) transmission. By …

Gordon and Mollenauer, in their famous paper published in 1990, laid out how the interplay
between the nonlinear Kerr effect in optical fibers and the amplified spontaneous-emission …

We study the performance of feed-forward equalizers (FFEs) and decision-feedback
equalizers (DFEs) in compensating chromatic dispersion and first-order polarization-mode …

We examine the performance of optical 8-ary differential phase-shift keying transmission
systems according to the type of receiver structure and modulation format. Compared with …

We review the time domain, frequency domain, and Fourier series Karhunen-Loeve series
expansion (KLSE) methods for exact BER evaluation in intensity-and phase-modulated …

Differential quadrature phase shift keying (DQPSK) modulation has become particularly
attractive in high-speed optical communications because of its resistance to fiber …
