“…To further expand the signal bandwidth beyond the C + L-band, SOAs whose gain spans continuously over 100 nm containing the C + L-band have been demonstrated to successfully amplify more than 100 Tb s −1 WDM signals [41]. A higher operating power with many WDM signals suppresses the SOA nonlinear gain dynamics (see section 3 of [37]).…”

“…In this context, increasing the capacity of telecommunication networks remains limited by bandwidth. All current commercial NTN solutions are based on the conventional RF systems for both feeder and user links operating at the Ku-band (12-18 GHz), the Ka-band (27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40), and the Q/V band (40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50). This still requires many units: for example, around 50 ground stations are required to reach a satellite capacity of 1 Tb s −1 with the traditional RF feeder links, and the number of these ground stations increases linearly with the system throughput [319].…”

The Covid-19 pandemic showed forcefully the fundamental importance broadband data communication and the internet has in our society. Optical communications forms the undisputable backbone of this critical infrastructure, and it is supported by an interdisciplinary research community striving to improve and develop it further. Since the first ‘Roadmap of optical communications’ was published in 2016, the field has seen significant progress in all areas, and time is ripe for an update of the research status. The optical communications area has become increasingly diverse, covering research in fundamental physics and materials science, high-speed electronics and photonics, signal processing and coding, and communication systems and networks. This roadmap describes state-of-the-art and future outlooks in the optical communications field. The article is divided into 20 sections on selected areas, each written by a leading expert in that area. The sections are thematically grouped into four parts with 4–6 sections each, covering, respectively, hardware, algorithms, networks and systems. Each section describes the current status, the future challenges, and development needed to meet said challenges in their area. As a whole, this roadmap provides a comprehensive and unprecedented overview of the contemporary optical communications research, and should be essential reading for researchers at any level active in this field.

“…Another main disadvantage of SOAs in terms of amplification performance comes from the short lifetime of the upper level carriers, associating the SOAs with undesirable large gain compression and pattern effects, especially at multi tens of Gbaud line rates. As a result, all these SOAs' nonlinearities cause severe signal degradations that dictate the appliance of heavy digital signal processing (DSP) at the receiver side [8] for signal regeneration.…”

The increasing need for more efficient communication networks has been the main driving force for the development of complex photonic integration circuits combining active and passive building blocks towards advanced functionality. However, this perpetual effort comes with the cost of additive power losses and the research community has resorted to the investigation of different materials to establish efficient on-chip amplification. Among the different proposals, erbium-doped waveguide amplifiers appear to be a promising solution for high performance transmission in the C-band band with low fabrication cost, due to their CMOS compatibility and integration potential with the silicon\silicon nitride photonic platforms. In this paper we provide a holistic study for high-speed WDM transmission capabilities of a monolithically integrated Al2O3:Er 3+ spiral waveguide amplifier co-integrated with Si3N4 components, providing a static characterization and a dynamic evaluation for (a) 4×40 Gbps, (b) 8×40 Gbps and (c) 8×60 Gbps WDM transmissions achieving clearly open eye diagram in all cases. The active region of the erbium doped waveguide amplifier consists of a 5.9 cm Al2O3:Er 3+ spiral adiabatically coupled to passive Si3N4 waveguides combined with on chip 980 nm/1550 nm WDM Multiplexers/Demultiplexers. Experimental results reveal bit-error rate values below the KR4-FEC limit of 2×10 -5 for all channels, without any DSP applied on the transmitter or receiver side for a 4×40 Gbps and 8×40 Gbps data stream transmission.
