“…In the process of migrating to a higher port count WSS without introducing a complex configuration or loss increase entails the use of planar lightwave circuits (PLCs) [261]. The design and fabrication of siliconbased integrated multichannel filter cascaded by a wavelength de-multiplexer has been reported by numerous groups [262], [263], [264]. The multichannel filtering is achieved by a DI structure and the de-multiplexing is performed by an AWG.…”

“…The multichannel filtering is achieved by a DI structure and the de-multiplexing is performed by an AWG. Many other methods can also perform the desired functions, such as the dielectric multilayered filters [262], the photonic crystal based drop filter [263], and the plasmonic nanodisk cavities [264]. One of the main issues with this technique is that the channel count in the demonstrations to date are pretty low.…”

Abstract-Elastic optical networks (EON) have been proposed to meet the network capacity and dynamicity challenges. Hardware and software resource optimization and re-configurability are key enablers for EONs. Recently, innovative multi-carrier transmission techniques have been extensively investigated to realize high capacity (Tb/s) flexible transceivers. In addition to standard telecommunication lasers, optical carrier generators based on optical frequency combs (OFC) have also been considered with expectations of reduced cost and inventory, improved spectral efficiency and flexibility. A wide range of OFC generation techniques have been proposed in the literature over the past few years. It is imperative to summarize the state of the art, compare and assess these diverse techniques from a practical perspective. In this survey, we identify salient features of optical multicarrier generators, review and compare these techniques both from a physical and network layer perspective. OFC demultiplexing/filtering techniques have also been reviewed. In addition to transmission performance, the impact of such sources on the network performance and real-world deployment strategies with reference to cost, power consumption, and level of flexibility have also been discussed. Field trials, integrated solutions, flexibility demonstrations are also reported. Finally, open issues and possible future directions that can lead to real network deployment are highlighted.

“…Fig. 3 shows in details the experimental setup employed for the BER measurements in the WDM configuration [11]. It must be pointed out that the setup for the single channel measurement is the same, except that in this case only the source pertinent to the examined path (channel under test) is active.…”

The performance of a ring-resonator based passive wavelength router, suitable for optical networking at chip level, is evaluated through bit error rate measurements in single channel 10 Gb/s and 3-channel 10 Gb/s WDM configurations. As the routing path involves a different number of routing elements, depending on the wavelength used for the propagating signal, the performance of three output ports with respect to a specified input one are experimentally evaluated and discussed. Measurements show that low rejection on the filter elements due to fabrication issues mostly affect the channel on the through path with respect to the dropped ones

“…To realize smaller WDM demultiplexers, those based on Si PC are being developed. [17][18][19][20][21][22][23][24] For example, Song et al 18 demonstrated two-dimensional (2-D) PC cavities-based 16-channel WDM demultiplexer with 628-GHz channel spacing, and the footprint of per channel is 12 μm 2 . Takahashi et al 21 demonstrated 2-D PC cavities-based 32-channel out-of-plane WDM demultiplexer with 100-GHz channel spacing, and the footprint of per channel is ∼130 μm 2 .…”

We propose a design for silicon-on-chip integrated eight-channel wavelength division multiplexing (WDM) demultiplexer, which consists of parallel-arrayed one-dimensional (1-D) photonic crystal nanobeam cavities (PCNCs) with high-Q over 10 5 and large free spectral range of ∼200 nm. To the best of our knowledge, this is for the first time that a 1-D PCNC-based demultiplexer is presented. The performance of the device is investigated theoretically by using three-dimensional finite-difference time-domain method. To enable eightchannel parallel arrayed 1-D PCNCs to be coupled to on-chip optical networks for higher integration and multiplex application, an 1 × 8 taper-type equal optical power splitter is used to connect all channels simultaneously. The total device footprint is as small as 12 μm × 15 μm (width × length), which is decreased by five times compared to that per channel in the recent two-dimensional (2-D) PC-based demultiplexer. Moreover, the average channel spacing smaller than 115 GHz is achieved, which is more than two times smaller than that of 2-D PC nanocavity devices, demonstrating that the arrayed nanocavities have the potential for developing ultracompact 100-GHz spaced filters in a dense WDM system. Thus, we believe that the results demonstrated in this work is promising for the future on-chip photonics integrated circuits and optical communication systems.
