We demonstrate a novel polarization-division multiplexed differential quadrature phase-shift keying receiver. It has the minimum number of analog controls and an integrated polarization interference monitor for polarization tracking. It can theoretically tolerate polarization-dependent loss in the link. We achieve ∼10 times tracking speed improvement, ∼6-dB lower loss, and ∼100 times lower average bit-error rate during most of the tracking over our previous work for 43-Gb/s PDM-DQPSK.

“…An N × M gridless WSS is another requirement to provide BV-ROADM nodes with colorless, directionless and contention-less operation. An N × M gridless WSS has been proposed and demonstrated by Bell Laboratories; configured to realize 5 fully connected ports with minimum channel spacing of 50 GHz, it uses essentially the same component building blocks as the conventional 1xN WSSs and has the same footprint [41].…”

SUMMARYMany detailed studies ranging from networking to hardware as well as standardization activities over the last few years have advanced the performance of the elastic optical network. Thanks to these intensive works, the elastic optical network has been becoming feasible. This paper reviews the recent advances in the elastic optical network from the aspects of networking technology and hardware design. For the former, we focus on the efficient elastic network design technology related to routing and spectrum assignment (RSA) of elastic optical paths including network optimization or standardization activities, and for the latter, two key enabling technologies are discussed: elastic transponders/regenerators and gridless optical switches. Making closely-dependent networking and hardware technologies work synergistically is the key factor in implementing truly effective elastic optical networks. key words: elastic optical network, network design, routing and spectrum assignment, elastic transponder

“…These devices cannot be used in short reach networks such as networks on chip or in board to board or data center interconnects due to their volume. The flexible-grid WSS based on AWG described in [6] requires a complex fabrication process and hardly achieves a very narrow steep-edge flat-top passband.…”

The physical characteristics of microring resonator switching devices are thoroughly analyzed using a model based on the field coupling matrix theory. The spectral response and insertion loss properties of these switching elements are simulated using the developed model. Results show that by cascading three microring resonators it is possible to achieve flat-top passband widths ranging from 6.25 GHz to 3 THz, while having insertion losses compatible with the use in flexible-grid optical communication networks. In light of a potential use of these devices in the design of a scalable flexible wavelength selective switch, the architecture of simple optical switches with limited functionalities is discussed.
