“…For example, regarding amplification, praseodymium-doped fibre amplifier (PDFA), neodymium DFA (NDFA), thulium DFA (TDFA), and erbium DFA (EDFA) could be considered for the O-band, E-band, S-band, and C+L-bands, respectively, [29]. Alternative solutions based on bismuth DFA, Raman amplifiers, or semiconductor optical amplifiers (SOA) can also be exploited [30]. All this poses new considerations and requirements in the design and implementation of novel MB transmission systems.…”

In the last 15 years, global data traffic has been doubling approximately every 2–3 years, and there is a strong indication that this pattern will persist. Hence, also driven by the emergence of new applications and services expected within the 6G era, new transmission systems and technologies should be investigated to enhance network capacity and achieve increased bandwidth, improved spectral efficiency, and greater flexibility to effectively accommodate all the expected data traffic. In this paper, an innovative transmission solution based on multiband (MB) over spatial division multiplexing (SDM) sliceable bandwidth/bitrate variable transceiver (S-BVT) is implemented and assessed in relation to the provision of sustainable capacity scaling. MB transmission (S+C+L) over 25.4 km of 19-cores multicore fibre (MCF) is experimentally assessed and demonstrated achieving an aggregated capacity of 119.1 Gb/s at 4.62×10−3 bit error rate (BER). The proposed modular sliceable transceiver architecture arises as a suitable option towards achieving 500 Tb/s per fibre transmission, by further enabling more slices covering all the available S+C+L spectra and the 19 cores of the MCF.

“…9 Alternative solutions based on bismuth DFA, Raman amplifiers, or semiconductor optical amplifiers (SOA) are also gaining special attention due to its lower cost. 11 In fact, Raman amplification has been demonstrated to be a flexible solution that offers an ultra-wide gain profile enabling operation across a wide range of wavelengths. 12 However, in general, adopting technologies tailored for specific bands beyond the traditional C-band are often accompanied by higher implementation costs.…”

Innovative multi band (MB) sliceable bandwidth/bitrate variable transceivers (S-BVTs) are proposed for future adoption in next-generation optical networks towards targeting the expected capacity scaling driven by the increasing traffic demand and emergence of new 6G services and applications with stringent requirements. To provide enhanced bandwidth/capacity and energy efficiency to support the envisioned growing demand, the use of MB technology is proposed and experimentally assessed up to 75 km of standard single mode fiber (SSMF) considering programmable MB S-BVTs. We demonstrate an aggregated capacity of 132.2 Gb/s exploiting S+Cbands and scalability towards enabling multi-Tb/s transmission within the metro/aggregation network segment. The sliceability of the MB S-BVT is demonstrated considering joint MB transmission (S+C) up to 2-hops network path of 75 km and an additional span of 50 km of SSMF for the C-band contribution. Different configurations based on single side band (SSB) and double side band (DSB) modulation and amplification technologies have been evaluated according to the particular scenario and band of operation. Finally, the programmability of the presented MB transceiver is also assessed as a key capability to promote network automation and flexibility. On this regard, a software-defined networking (SDN) agent based on open data model, such as OpenConfig, is implemented and validated to suitably reconfigure the transceiver according to the network requirements/demand. Key operational transceiver mode capabilities and configuration constraints, for the agent's implementation, are identified towards supporting MB transmission within future optical networks.

“…This leads to SOAs having lower costs, lower power dissipation, and smaller size, with the added advantages of both linear and nonlinear functionalities, and large-scale monolithic integration capability with silicon components and integrated circuits [4]. In addition, SOAs are implemented for a large selection of wavelength ranges depending on the materials used, including all wavelengths across the T-band (1130 nm), O-band (1300 nm), S-band (1500 nm), C-band (1550 nm), and L-band (1600 nm) [5,6]. To enhance the properties of SOAs, quantum dot/dash (QD) gain materials have been exploited with much improved performance over those using quantum wells (QWs).…”

We present here a performance comparison of quantum-dash (Qdash) semiconductor amplifiers (SOAs) with three, five, eight, and twelve InAs dash layers grown on InP substrates. Other than the number of Qdash layers, the structures were identical. The eight-layer Qdash SOA gave the highest amplified spontaneous emission power (4.3 dBm) and chip gain (26.4 dB) at 1550 nm, with a 300 mA CW bias current and at 25 °C temperature, while SOAs with fewer Qdash layers (for example, three-layer Qdash SOA), had a wider ASE bandwidth (90 nm) and larger 3 dB gain saturated output power (18.2 dBm) in a shorter wavelength range. The noise figure (NF) of the SOAs increased nearly linearly with the number of Qdash layers. The longest gain peak wavelength of 1570 nm was observed for the 12-layer Qdash SOA. The most balanced performance was obtained with a five-layer Qdash SOA, with a 25.4 dB small-signal chip gain, 15.2 dBm 3 dB output saturated power, and 5.7 dB NF at 1532 nm, 300 mA and 25 °C. These results are better than those of quantum well SOAs reported in a recent review paper. The high performance of InAs/InP Qdash SOAs with different Qdash layers shown in this paper could be important for many applications with distinct requirements under uncooled scenarios.
