In this paper we present simulation results comparing the performance of CMA and backpropagation to compensate the chromatic dispersion in a NGPON with QPSK phase modulation
and coherent detection.
Therefore, while choosing the frequencies of the tones for pump phase modulation
it is required to find a compromise between the efficiency of SBS mitigation and idler spectral broadening, or to implement one of the techniques designed to reduce broadening of the idler spectrum , .
As discussed above, the function of the phase shifter can be replaced by the control of initial phase modulation
of DDS generated waveforms.
As long as the total phase modulation
is much less than a radian, the spectrum corresponding to each modulating frequency [f.
Solving the cross phase modulation
was critical to adoption of coherent technology in metro networks," commented Arun Zarabi, vice president, Cortina Systems, Inc.
In order to reach the needed sensitivity we will setup a novel phase modulation
technique including lock-in demodulation in combination with mass-resolved ionization and photoelectron detection.
RSOA bias dithering was proposed as a new method for using of amplitude-to-phase modulation
in an active RSOA material ,  and phase modulation
in laser .
The topics include analogue performance metrics, sources of noise in fiber optic links, propagation effects, external intensity modulation with direct detection, external phase modulation
with interferometric detection, other analog optical modulation methods, and high current photodetectors.
Materials and Processes continues with papers from the Hellenic Institute of Holography on use of its ZZZyclops transportable colour holography camera, Geola discussing pulse laser holograms on photoresist, diffracting hololenses from the Royal Military College of Canada (a newcomer to this conference) and phase modulation
in collinear holographic storage (Beijing Institute of Technology).
A promising solution to our issue is to employ phase detection to measure the phase modulation
accompanying the plasmon excitation.
Chosen for "best" awards were papers in the fields of CAD, tools, and test; they deal, respectively, with digital ground bounce reduction by phase modulation
of the clock; poor man's TBR--a simple model reduction scheme; and wrapper design for testintg IP cores with multiple clock domains.
Downconversion Techniques Conversion Method Pros and Cons Fundamental Mixing Preserves amplitude and phase modulation
