Performance characteristics are obtained for various optimum and suboptimum photocounting array receiver structures obtained in the preceding paper (Part 1). Probability of error curves are presented for the case of lognormal fading and for a variety of receiver configurations including the BPCM single-detector and array-detector processors and the BPOLM and BPIM single-detector processor. In a...

We examined optical fibers suitable for avoiding such problems as the fiber fuse phenomenon and failures at bends with a high power input. We found that the threshold power for fiber fuse propagation in photonic crystal fiber (PCF) and hole-assisted fiber (HAF) can exceed 18 W, which is more than 10 times that in conventional single-mode fiber (SMF). We considered this high threshold power in P...

Communication traffic is increasing continuously along with the expansion of video streaming service and the popularization of smartphones and other mobile devices requiring high-speed, large-capacity transmission. Digital coherent optical communication technology using multilevel modulation formats has already been used for long haul systems and is now attracting attention as a means of long-d...

Abstract In this paper we present optical communication multibus system including: physical topology, logical topology, structure of central control unit (CCU). We describe the task of CCU: analyze the state of logical buses, topology reconfiguration, system structures clustering, unexpected events handling, statistic gathering, etc. In this paper we present synthesis of core system network bas...

The performance of direct and hetedyne detection optical intersatellite communication links are evaluated and compared. It is shown that the perfonnance of optical links is very sensitive to the pointing and tracking e m at the transmitter and receiver. In the presence of random pointing and tracking errors, optimal antenna gains exist that wiU minimize the required transmitter power. In additi...

In recent years Optical soliton technologies have attracted much interest in the academic and industrial worlds. Today the potential of soliton engineering is recognised world-wide with reasearch groups actively working on this topic in every part of the globe. In this report, we present a brief overview of the fundamental concepts of temporal solitons and its potential applications in the eld ...

Method for applying spread-spectrum techniques to optical communication is presented. The interference suppression capability of spread-spectrum systems is shown to be enhanced by optical transform domain processing.Effects of jammer in DSSS communication system are demonstrated in thispaper.Several possible implementations of this system are suggested, and applications to fiber optics, laser r...

In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...
