Beschreibungen

<P>Fiber-optic communication systems have revolutionized our telecommunication infrastructures – currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information – only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored.</P>
<P>As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics:</P>
<P>- The transmitter and receiver for phase-modulated coherent lightwave systems</P>
<P>- Method for performance analysis of phase-modulated optical signals</P>
<P>- Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects</P>
<P>- Wavelength-division-multiplexed direct-detection DPSK signals</P>
<P>- Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal.</P>
<P>Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field. </P>
