“…DCF is a good Raman gain medium due to its small effective core area (16 μm 2 ), which provides greater Raman gain per pump power unit. Some Raman systems have been previously demonstrated using a combination of Raman amplification in the transmission fiber and dispersion-compensating Raman amplifiers (DCRA) [42,43].…”

This work is meant to provide a review of different multiplexing topologies employing distributed erbium-doped fiber and Raman amplification to solve the problem of powerloss compensation in fiber-optic sensor (FOS) networks. This is a key parameter in large multiplexing networks, particularly when employing intensity-modulated sensors. These topologies are studied both theoretically and experimentally, and a comparative analysis is carried out between them. The main parameters considered in the analysis are power budget, optical signal-tonoise ratios, scalability and architecture complexity.Comparison of the measured optical spectrum of amplified single and double bus networks for sensor multiplexing.

Представлен обзор истории разработки и применения ВКР-усилителей, включая распреде-ленные, дискретные (или точечные) и гибридные ВКР-усилители. Рассмотрен принцип работы ВКР-усилителя, физические механизмы спонтанного комбинационного рассеяния света (КРС) и вынужденного комбинационного рассеяния света (ВКР). Приведены формулы для расчета коэф-фициента усиления слабого сигнала в процессе ВКР в телекоммуникационном волокне, а также коэффициента усиления с учетом насыщения. Приведена экспериментальная зависимость коэф-фициента комбинационного усиления материала от разности частот накачки и сигнала для кварце-вого волокна. Рассмотрены схемы оптических систем связи с распределенными ВКР-усилителями с разными вариантами накачки, а также ВКР-усилители с полихроматической накачкой. В заключе-ние проанализированы преимущества и недостатки применения ВКР-усилителей в системах связи.Ключевые слова: ВКР-усилитель, рамановский усилитель, ON/OFF-усиление, двунаправ-ленная накачка, многокаскадная накачка, полихроматическая накачка. RAMAN AMPLIFIERS IN OPTICAL COMMUNICATION SYSTEMSAn overview of the history of development and application of Raman amplifiers is provided (including distributed, discrete and hybrid Raman amplifiers). The principle of Raman amplifier is discussed, as well as physical mechanisms of spontaneous Raman scattering (RS) and stimulated Raman scattering (SRS). The formulas are presented for calculating of the SRS small-signal gain in the telecommunication fiber, and for calculating of the SRS gain taking into account the saturation. The experimental dependence of the Raman gain of the material on the difference between the pumping frequency and signal frequency for quartz fiber is shown. Schemes of optical communication systems with distributed Raman amplifiers with different methods of pumping are discussed, as well as Raman amplifiers with polychromatic pumping. In conclusion, the advantages and drawbacks of implementation of the Raman amplifiers in communication systems are analyzed.

“…61), reported coherent-PSK [158,[164][165][166] suffers ∼5 dB greater implementation penalties than preamplified RXs [13,15,[128][129][130]133,135,159], eliminating much of the theoretical benefit. While improved PSK designs may achieve the anticipated sensitivities, based on existing demonstrations, preamplified RX designs have exhibited superior sensitivity and datarate, as well as WDM scalability [135,138,139,149,167].…”

“…For high-rate 100+ channel WDM-DPSK systems (e.g., [138][139][140]167,447]), the size, weight, power, and costs associated with reliably maintaining a stable delay-line interferometer for each channel can be substantial. Miyamoto and coauthors [149,151] demonstrated concurrent PSK to ASK conversion of 43 Gbit/s WDM-DPSK channels to WDM-duobinary channels on the 100 GHz ITU grid using a 50-GHz free-spectralrange (FSR) DI.…”

Free-space laser communication systems have the potential to provide flexible, high-speed connectivity suitable for long-haul intersatellite and deep-space links. For these applications, power-efficient transmitter and receiver designs are essential for cost-effective implementation. State-of-the-art designs can leverage many of the recent advances in optical communication technologies that have led to global wideband fiber-optic networks with multiple Tbit/s capacities. While spectral efficiency has long been a key design parameter in the telecommunications industry, the many THz of excess channel bandwidth in the optical regime can be used to improve receiver sensitivities where photon efficiency is a design driver. Furthermore, the combination of excess bandwidth and average-power-limited optical transmitters has led to a new paradigm in transmitter and receiver design that can extend optimized performance of a single receiver to accommodate multiple data rates. This paper discusses state-of-the-art optical transmitter and receiver designs that are particularly well suited for average-power-limited photon-starved links where channel bandwidth is readily available. For comparison, relatively simple direct-detection systems used in short terrestrial or fiber optic links are discussed, but emphasis is placed on mature high-performance photon-efficient systems and commercially available technologies suitable for operation in space. The fundamental characteristics of optical sources, modulators, amplifiers, detectors, and associated noise sources are reviewed along with some of the unique properties that distinguish laser communication systems and components from their RF counterparts. Also addressed is the interplay between modulation format, transmitter waveform, and receiver design, as well as practical tradeoffs and implementation considerations that arise from using various technologies.
