For the first time, interoperability is demonstrated at 100G with modern CFP-DCO and CFP2-DCO interfaces using the newly standardized Staircase FEC between three vendors and two DSP-ASIC providers. Inter-workable 100G WDM transmission (up to 1200 km) and passive point-to-point interconnection (up to 135 km) are shown.

For the first time, a 100/200-Gbps DP-QPSK/8QAM/16QAM silicon photonic DCO-CFP2 interface using various FECs and consuming less than 19 Watts is presented and evaluated. Performances make the transceiver compliant with DCI, metro/regional, LH, and ULH applications.

For the first time, we show that 100G coherent digital CFP is efficient to address short-reach (<;150 km), regional (<;1000 km), and ultra long-haul (~2000 km) transmission applications with half the cost, one third the power consumption and one quarter the size of common 100G WDM interfaces.

We discuss opportunities that silicon photonics offers for metro and regional reach dense wavelength division multiplexing (DWDM) transceivers operating at 100G and beyond. In particular, we describe the unique advantages provided by silicon photonics for transceivers based on coherent detection.

First high-speed all-optical wavelength converter, with monolithically integrated delay loop and high extinction-ratio tuning abilities in a simple configuration with only one semiconductor optical amplifier has been realized and successfully tested for 40 Gbit/s RZ format signals.

A novel 3R regenerator based on a single semiconductor optical amplifier in a delayed-interference configuration is presented and experimentally tested. The retiming capability of the device exceeds 6 ps at 10 Gb/s.

Transmission at 40 Gbit/s over 1700 km of non-zero dispersion fibre with 100 km amplifier spacing is reported for the first time. The demonstration is enabled by an all-fibre higher-order-mode dispersion-compensating module (HOM-DCM) and distributed Raman amplification.

A spectral efficiency of 0.53 b/s/Hz is demonstrated at 160 Gb/s over 400 km. The pseudo-linear transmission regime with 100% post compensation is used, and the transmission loss through the 100 km spans is compensated with distributed Raman amplification only.

We use a novel fiber-grating device to demonstrate the first polarization-insensitive all-fiber higher order mode dispersion compensator for broad-band dispersion compensation. Its low loss and high effective area have enabled transmission through 1000 km (10/spl times/100 km) of nonzero dispersion-shifted fiber (NZDSF) at 40 Gb/s.

All-optical wavelength conversion at bit rates from 10 up to 100 Gb/s is experimentally and theoretically investigated employing a fully-integrated semiconductor optical amplifier (SOA) delayed-interference (DI) configuration.

Dispersion management is becoming paramount in high-speed wavelength-division-multiplexed lightwave systems, that operate at per-channel rates of 40 Gb/s and higher. The dispersion tolerances, in these systems, are small enough that sources of dispersion variation, that are negligible in slower systems, become critically important to network performance. At these high-bit rates, active dispersion compensation modules may be required to respond dynamically to changes occurring in the network, such as variations in the per-channel power, reconfigurations of the channel's path that are caused by add-drop operations, and environmental changes, such as changes in ambient temperature. We present a comprehensive discussion of an emerging tunable dispersion compensating device, based on thermally actuated fiber gratings. These per-channel devices rely on a distributed on-fiber thin film heater, deposited onto the outer surface of a fiber Bragg grating. Current flowing through the thin film generates resistive heating at rates that are governed by the thickness profile of the metal film. A chirp in the grating is obtained by using a thin-film, whose thickness varies with position along the length of the grating in a prescribed manner; the chirp rate is adjusted by varying the applied current. The paper reviews some of the basic characteristics of these devices and their implementation, in a range of different applications, including the mitigation of power penalties associated with optical power variations. We present detailed analysis of the impact of group-delay ripple and polarization-mode dispersion on systems performance, and present results from systems experiments, that demonstrate the performance of these devices at bit rates of 10, 20, 40 and 160 Gb/s. We also discuss advantages and disadvantages of this technology, and compare to other devices.
