Transmission performance of ultra-dense 2.5-and 10-Gb/s nonreturn-to-zero intensity-
modulated direct-detection wavelength-division-multiplexing systems in various single …

Here we demonstrate theoretically that stimulated Brillouin scattering (SBS) can induce a
phase shift of the optical carrier relative to its sidebands due to the waveguiding effect of the …

We demonstrate the transmission of 51.56-Gb/s on-off keying (OOK) signals generated by
using a 1.55-μm directly modulated laser (DML) over 15-km long standard single-mode …

The dual modulation transmitter, where both the directly modulated laser (DML) and electro-
absorption modulator (EAM) are modulated, has attracted considerable attention due to its …

Nine different experimental techniques for measuring the linewidth-enhancement factor
alpha are discussed and tested on a single 760-nm vertical-cavity surface-emitting laser …

We report on the experimental demonstration of a GaAs IQ modulator. The device consists of
two “nested” Mach-Zehnder modulators for the inphase and quadrature component and is …

The dual modulation of a directly modulated laser (DML) and an electro-absorption
modulator (EAM) is known to be an effective way to generate an optical single sideband …

We report on technical challenges associated with the use of directly modulated lasers in the
mobile fronthaul networks based on radio-over-fiber (RoF) technology. In particular, the …

We present a simulation study on the chirping characteristics of a directly modulated 40
Gbps laser diode and evaluate its performance for use in high-speed optical fiber links. The …

We have derived an exact large-signal theory of propagation in a dispersive fiber of an
optical wave with sinusoidal amplitude and frequency modulation. This has been applied to …
