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 [14], [15].
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 [12], [13] and
phase modulation in laser [14].
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 Suitable for digital modulation Frequency Multiplication Economical Does not preserve amplitude modulation Frequency and
phase modulation magnified by the multiplication factor Table 2.
