This paper will review and discuss pico-and femtosecond pulse generation from passively
modelocked vertical–external-cavity surface-emitting semiconductor lasers (VECSELs). We …

The prospects for using fiber optical parametric amplifiers (OPAs) in optical communication
systems are reviewed. Phase‐insensitive amplifiers (PIAs) and phase‐sensitive amplifiers …

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

We review and study several single carrier based multi-level and multi-dimensional coding
(ML-MDC) technologies recently demonstrated for spectrally-efficient 100-Gb/s transmission …

Differential phase-shift keying (DPSK) has attracted significant attentions in research and
development during the last several years. An overview of DPSK for high spectral efficiency …

This paper highlights certain optical signal processing (OSP) functions that can be achieved
when using optical frequency combs. An optical frequency comb can provide many narrow …

Analytical formulas for the power spectra of return-to-zero (RZ) optical signals generated by
Mach-Zehnder (MZ) modulators are derived. Pulse duty cycles of 33%, 50%, and 67%, in …

In an all-Raman amplified, recirculating loop containing 100-km spans, we have tested
dense wavelength-division multiplexing at 10 Gbits/s per channel, using dispersion …

The Raman response of germanosilicate fibers is presented. This includes not only the
material dependence but also the relation between the spatial-mode profile of the light and …

The error probability is derived analytically for differential phase-shift keying (DPSK) signals
contaminated by both self-and cross-phase modulation (SPM and XPM)-induced nonlinear …
