“…VCSEL technology appears very promising in terms of cost, testability, and power consumption [10], but for its exploitation in applications such as MANs it is necessary to guarantee long-wavelength single-mode emission to limit the effect of modal and chromatic dispersion (CD) and to support dense WDM [11,12]. In PASSION project the company Vertilas GmbH has developed VCSEL sources in InP satisfying the above requirements [13]. Single-mode operation is achieved by an appropriate transverse waveguide structure with sidemode suppression ratio higher than 35 dB and a stable polarization output.…”

Innovative photonic solutions designed and developed in the H2020 research project PASSION are presented for the future metropolitan area network (MAN) supporting different aggregated data traffic volumes and operating at heterogenous granularities. System performance evaluated both by simulations and experimentation regarding the proposed vertical cavity surface emitting laser (VCSEL) -based modular sliceable bandwidth/bitrate variable transceiver (S-BVT) are shown in realistic MANs organized by hierarchical levels with the crossing of multiple nodes characterized by new switching/aggregation technologies. The capabilities and challenges of the proposed cost-effective, energy-efficient and reduced footprint technological solutions will be demonstrated to face the request of huge throughput and traffic scalability.

Beyond 50 Gb/s Directly-Modulated Long-Wavelength VCSELs for Next-Gen Access Network

Abstract: The employment of long-wavelength directlymodulated VCSELs for applications in next-generation access networks is proposed. Suitable simulations are shown in case of DMT modulation and SSB filtering, demonstrating the capabilities of LW-VCSEL for future 50-Gb/s access networks.
