We demonstrate the superiority of digital nonlinear pre-compensation over post-compensation for unrepeated single-carrier 28Gbaud PM-16QAM Raman-amplified system. We show that transmitter side digital-back-propagation (DBP) combined with optimized Raman pump configurations enables unrepeated transmission over 420 km.
We studied the properties of 2×2 photonic switching elements made of two intersecting waveguides coupled with two micro-rings and showed that they can exhibit the effect of coupled-resonator induced transparency (CRIT). Employing the CRIT effect promises reduction of power consumption compared to standard switching techniques, and thus, the potential of utilizing a fast (but weak) electro-optic effect...
We show how to estimate accurately the Jones matrix of the transmission line by analyzing the Stokes vector of DP-QPSK signals. Our method can be used to perform in-situ PMD measurements in polarization-multiplexed QPSK systems.
We present a framework for emulating dynamic network events and investigating the corresponding performance impact with a two-step approach consisting of parametric modeling of slowly varying effects and detailed bit-level simulations and discuss various application examples.
Key issues related to the design of electro-optic transmitters and receivers are discussed in this paper. These topics include limitations in 100G transmission systems resulting from the frequency response of devices and non-linear effects. Numerical simulations illustrate the importance of realistic modeling in such high-speed systems.
We present methods for accurately modeling high-speed optical transmission systems with channel data rates beyond 40 Gbit/s. We provide simulation guidelines and examples for investigating limitations of transmitter and receiver, fiber impairments, and estimating signal performances.
This paper shows how sophisticated modeling techniques allow the efficient design and optimization of optical links that support the transport of broadband services in wireless networks. Application examples studying various technologies are presented to demonstrate the value of photonic design automation during the design and development stages of network roll-outs and upgrades
Summary form only given. By using four-wave mixing (FWM) experiments we characterized the fast nonlinearities in a semiconductor laser amplifier (SLA). We extracted the parameters of the relevant dynamic processes with a new technique that eliminates an ambiguity resulting from a dependence on saturation conditions. Additionally this technique enabled us to allow for gain dispersion effects which...
