“…When increasing the cavity length, the cavity mode spacing proportionally decreases, thus the number of cavity modes under the spectrum envelope increases: thousands of modes for the short cavities increase to hundreds of thousands for the km-long ones. The presence of a higher number of modes increases the transmitter RIN, which is the cause of BER floor rising, with floors at higher BERs for longer cavities [6].…”

“…Due to the presence of a HPDG device, a two-Faraday topology is exploited to ensure stability of the signal state of polarization (SOP) Manuscript within the optical cavity, which is established between the optical reflector at the remote node (RN) and the mirror at the reflective semiconductor optical amplifier, placed at the optical network unit (ONU) [3]. Recent works [4]- [6] have demonstrated the effectiveness of this approach to cope with the SOP evolution due to the unavoidable birefringence associated with the distribution fiber, which connects the ONU and the RN WDM multiplexer, namely an arrayed waveguide grating (AWG). The authors demonstrated operation of the two-Faraday rotator-based optical circuit up to 10 Gb/s for different AWG full width half maximum (FWHM) channel bandwidth, nevertheless the interplay between the self-tuning transmitter chirp and the feeder fiber chromatic dispersion significantly limited the transmission reach in standard single mode fibers (SSMF).…”

Operation of a network-embedded colorless selftuning transmitter for wavelength division multiplexing (WDM) networks is experimentally demonstrated at 10-Gb/s data rate. Colorless operation is achieved by self-seeding an O-band reflective semiconductor optical amplifier (RSOA) with the feedback signal reflected at the remote node WDM multiplexer filter. In particular, the transmitter exploits a 2-Faraday rotators configuration to ensure polarization insensitive operation and allowing for the exploitation of high gain O-band RSOAs, which present a very high polarization dependent gain. Two different multiplexers and various lengths of drop fibers constituted the network-embedded transmitters. Transmission up to 72 km of standard single mode fiber has been demonstrated at 10 Gb/s, confirming the absence of chromatic dispersion penalties as expected from the choice of the O-band operation. Index Terms-Passive optical network (PON), reflective semiconductor optical amplifier (RSOA), colorless transmitter, fronthaul.

“…Recently, a more simple and cost-effective network topology was introduced that incorporates self-seeded RSOA-fiber cavity lasers (RSOA-FCLs) [1], [6], [7]. The resonant laser cavity is formed by the distribution network between the RSOA's reflective facet and a mirror at the remote node (RN).…”

Reflective semiconductor optical amplifier (RSOA) fiber cavity lasers are attractive colorless, self-seeded, self-tuning, and directly modulatable sources for passive optical networks (PONs). They comprise of an RSOA in the optical network unit as the active element, a distribution fiber as the laser cavity, a waveguide grating router, and a common reflective mirror with the latter two positioned at the remote node. In this paper, we introduce a model and perform simulations to elucidate the recently discovered successful operation of this new PON source. The results are in agreement with experiments; the formation of a narrow laser spectrum with a relatively constant output power is seen despite a relatively broad passband window of the waveguide grating router. We further study mode competition and mode partition noise. It is shown that proper chromatic dispersion management can overcome mode partition noise limitations. The quality of the RSOA fiber cavity laser does not degrade when being directly modulated and as a result these highly multimode lasers offer an economic way to transport Gbit/s upstream data over kilometers of fiber in a wavelength division multiplexing-PON.

“…Moreover, to allow for the optical distribution network (ODN) fiber plant reuse, which is unavoidable in already deployed infrastructures, the drop and feeder fibers are standard single-mode fibers (SSMF). This choice clearly raises an issue for high-bit-rate comparison between C-and O-band transmitters as it has been shown that, due to the chirp, dispersion loads significantly affect the 10-Gb/s performance in terms of reach, i.e., feeder-fiber length and cavity length, i.e., ONU distance from the RN, which is the drop fiber length [5,6].…”

We propose a network-embedded colorless self-tuning transmitter for wavelength division multiplexed (WDM) networks based on self-seeding in reflective semiconductor optical amplifiers (RSOAs). We compare up to a 10-Gb/s data rate in either O-band or C-band operation. In particular, the transmitter exploits a two-Faraday rotator configuration to ensure polarization-insensitive operation and allowing for the exploitation of high-gain C-and O-band RSOAs, which present a very high polarization-dependent gain. Two different multiplexers and various lengths of drop fibers constituted the networkembedded transmitters in order to evaluate various dispersion load influence on cavity buildup. Moreover, transmission over standard single-mode feeder fiber has been evaluated both at 2.5 and 10 Gb/s to compare the performance in both bands, confirming the absence of chromatic dispersion penalties for the O-band operation. Index Terms-Chromatic dispersion; Colorless optical transmitter; Reflective semiconductor optical amplifier (RSOA); WDM passive optical networks (PON).
