“…The flexibility of the optical transmitter is further enhanced using multi-carrier technologies. Several studies have demonstrated multi-carrier solutions such as electrical and optical orthogonal frequency division multiplexing (OFDM) [32][33][34], Nyquist wavelength division multiplexing (N-WDM) [35] and optical arbitrary waveform generator (OAWG) [36]. Additionally in [2], the implementation of BVTs for EONs using various multi-carrier technologies has been discussed.…”

Flexible optical networks will provide the required service diversity to manage unpredictable traffic patterns and growth. However, a key challenge is to quantify flexibility in order to indicate the associated performance of individual components and subsystems required to support networks and correlate it with other figures of merit. Measurable key performance indicators will aid the process towards the design and deployment of cost effective and efficient optical networks. Moreover, the design and placement of network elements within a network influences the resultant network-wide flexibility and performance. In this paper, we highlight critical design parameters for key optical components, optical transmission and switching subsystems using flexibility as an additional figure of merit. We derive models to measure the flexibility of key optical components, optical transmission and switching subsystems based on entropy maximization. Using these models, we evaluate flexibility and design trade-offs of the presented enabling technologies with other key performance indicators such as spectral efficiency, lightpath reach, total capacity, normalized cost, connectivity and others. This study provides an advanced and more informed set of design rules that quantify and visualize the different degrees of flexibility of enabling technologies and associated performance based on required specification and/or functionality.

“…In the case of a link failure in the network, flexible-bandwidth networks are more adaptive and likely to have spare spectrum to allocate the re-routed signal, ensuring a high survivable restoration compared to conventional optical networks. EONs employ coherent optical orthogonal frequency division multiplexing (CO-OFDM) [11,12], coherent optical WDM (CO-WDM) [13], or Nyquist-WDM technologies [14], and adopt various modulation formats depending on the reach. More recently, UC Davis team has demonstrated dynamic optical arbitrary waveform generation (OAWG) and optical arbitrary waveform measurement (OAWM) [15,16]-based EON, which have overcome a number of limitations of CO-OFDM, CO-WDM, and Nyquist-WDM technologies, providing opportunities for new architectures to be implemented [9,15].…”

This paper discusses architecture, protocol, technologies, systems, and networking testbed for softwaredefined elastic optical networking in temporal, spectral, and spatial domains. By exploiting the progress in elastic optical networking (EON) in temporal and spectral domains utilizing dynamic optical arbitrary waveform generation and measurement technologies, and by extending the EON concept into the spatial domain through the new orbital angular momentum-based spatial division multiplexing, we realize EON exploiting elasticity in temporal, spectral, and spatial domains (3D-EON). Routing, spectral, spatial mode, and modulation format assignment with fragmentation awareness as well as hitless defragmentation for high capacity, high quality of service, and resource-efficient networking will be pursued. OpenFlow-based 3D-EON testbed at UC Davis includes optical supervisory channel with optical performance monitoring for software-defined networking with an adaptive observe-analyze-act cycle.

“…Even though the capacity of a transmission system can be increased by incorporating higher-order modulations, such as PM-16QAM or PM-64QAM [1], it becomes more susceptible to noise, and its reach also decreases as the modulation order increases. In this regard, optical super-channel technology can be viewed as a strong candidate to satisfy tangible Tb/s transmission, where coherently generated, dense multiple carriers are demultiplexed and decoded by orthogonal frequency multiplexing (OFDM) [2], or by Nyquist wavelength division multiplexing [3]. In a super-channel transmission system, the required capacity is usually attained by combining a large number of optical carriers, where each carrier maintains a certain phase relation to the others and is modulated at a lower bit rate, so as to be terminated at a receiver for a service interface [4].…”

Terabit-per-second (Tb/s) transmission capacity for the next generation of long-haul communication networks can be achieved using multicarrier optical super-channel technology. In an elastic orthogonal frequency division multiplexing (OFDM) super-channel transmission system, demultiplexing a portion of an entire spectrum in the form of a subband with minimum power is critically required. A major obstacle to achieving this goal is the analog-to-digital converter (ADC), which is power-hungry and extremely expensive. Without a proper ADC that can work with low power, it is unrealistic to design a 100G coherent receiver suitable for a commercially deployable optical network. Discrete Fourier transform (DFT) is often seen as a primary technique for understanding partial demultiplexing, which can be attained either optically or electronically. If fairly comparable performance can be achieved with an all-optical DFT circuit, then a solution independent of data rate and modulation format can be obtained. In this paper, we investigate two distinct OFDM super-channel receiver models, based on electronic and all-optical DFT-technologies, for partial carrier demultiplexing in a multi-Tb/s transmission system. The performance comparison of the receivers is discussed in terms of bit-error-rate (BER) performance.
