“…Most of the realizations were performed in the C band at 1.25 Gbit/s on transmission distances around 20 km. In particular, a prototype [20] and a field trial with standard frames [11] reached these values. The coexistence of time division multiplexing (TDM) and WDM PON supporting 512 users was studied in [4].…”

“…The mirror was placed after the demultiplexer, at the receiver side, removing the shared point. To overcome the added losses and improve the data cancellation, a saturated RSOA replaced the Faraday rotator mirror [11,23,24] in a so called "face to face" configuration. Thus, a distance of 70 km at 2.5 Gbit/s in the O band was achieved [24].…”

“…Thus, a distance of 70 km at 2.5 Gbit/s in the O band was achieved [24]. With the addition of two SOAs, a 125 km long cavity was accomplished [11]. By increasing considerably the cavity length, this configuration opens new perspectives.…”

“…We have recently managed to model the cavity [10], and fast gain compression in the gain medium has been identified as the key phenomenon enabling fast modulation. Some practical implementations have even been proposed for such a source, either for mobile front-haul [11] or WDM overlay for access networks [4]. In this paper, we will shortly describe the source, and explain why it can be called a laser.…”

The self-seeded cavity appeared in the last few years\ud as a colorless and low cost solution for wavelength division multiplexing\ud access. Although the self-seeded source presents a simple\ud architecture, its behavior has been misunderstood for a long time.\ud In this paper, we explain its operating principles and why we can\ud define such a source as a laser. We evidence a laser threshold and\ud show cavity modes for various lengths.We describe the conditions\ud required by the reflective semiconductor optical amplifier to sustain\ud the self-seeded cavity, by evaluating the choice of its epitaxial\ud structure and the influence of its optical confinement factor. An\ud analysis of the cavity behavior is given, pointing out that the relative\ud intensity noise results from the beating noise between the cavity\ud modes. An overview over the last performances in the C- as well as\ud in the O-band is then presented. Some practical applications are\ud reported. In particular, we detail themobile front-haul as a possible\ud employment for the self-seeded cavity to achieve a self-organized\ud wavelength network

“…The rapid growth in global telecommunications and in particular, optical fiber communications, has continued to fuel the deployment of fiber access networks that are located closer and closer to the end users [1][2][3] . Unfortunately, the cost and footprint of the existing access networks are still vital factors to be considered [1][2][3][4] .…”

Coherent ONU based on 850 μm-long cavity-RSOA for next-generation ultra-dense access network

et al. 2016

In this Letter, an efficient bidirectional differential phase-shift keying (DPSK)-DPSK transmission for a ultradense wavelength division-multiplexed passive optical network is proposed. A single distributed feedback laser at the optical network unit (ONU) is used both as the local laser for downlink coherent detection and the optical carrier for uplink. Phase-shift keying is generated using a low-cost reflective semiconductor optical amplifier (RSOA) at the ONU. The RSOA chip has the bandwidth of 4.7 GHz at the maximum input power and bias current. For uplink transmission, the sensitivity of the RSOA chip reaches −48.2 dBm at the level of bit error rate ¼ 10 −3 for back-to-back, and the penalty for 50 km transmission is less than 1 dB when using polarization diversity.
