“…There are at least two alternatives to the proposed system architecture, which can produce more than one carrier per optical source: spectrum-sliced systems [33,35] and systems, which are based on FWM use for producing third-order spectral components (without the initial carriers) [34,36]. Nevertheless, the use of idlers ω 4 produced by FOPA for doubling the number of carriers in WDM systems ensures the best carrier signal stability and, therefore, the highest quality of the transmittable signal.…”

Over the past two decades, a rapid expansion of the amount of information to be transferred has been observed. This tendency is explained by the rapid increase of Internet and other service users, as well as with the increasing availability of these services. This rapid growth in the amount of globally transmitted data is also associated with the expansion of the range of services offered, including such resource-consuming services as high-resolution video transmission, videoconferencing, and cloud computing, as well as with increasing popularity of such services. To satisfy this constantly increasing demand for higher network capacity, fiber optical transmission systems have been studied and applied with a growing intensity. Currently, optical transmission systems with wavelength-division multiplexing (WDM) have attracted much attention, as this technology allows using the available optical fiber resources more effectively than alternative technologies.

“…However, when using incoherent sources for spectrumsliced (SS)-WDM, intensity noise limits the performance and incurs bit error rate (BER) floors, yielding a tradeoff between the spectral efficiency and the bit rate. A rich body of research has examined the use of the nonlinear dynamics of semiconductor optical amplifiers (SOAs) to mitigate the intensity noise of a separate thermal source [5], [6].…”

“…For colorless ONU operation, the RSOA is remotely self-seeded by placing the FBG at the remote node (RN). We use a recently proposed balanced receiver (BR) that preserves noise cleaning [6]. Our RSOA/BR combination offers tight dense WDM wavelength packing, and is therefore best targeted as an innovative method for gradually upgrading existing PONs to SS-WDM with no modification to the passive splitter RN.…”

We present the use of an ultra-narrow spectrum-sliced incoherent light source for transmission of 10-Gb/s non-returnto-zero signals for wavelength-division-multiplexed passive optical networks. In this light source, a broadband amplified spontaneous emission noise is spectrum-sliced by an ultra-narrow filter and then fed to a gain-saturated semiconductor optical amplifier to suppress the excess intensity noise of the incoherent light. 10-Gb/s modulation is followed using a polarizationinsensitive optical modulator. Thanks to the ultra-narrow linewidth of the source (~0.01 nm), not only is the 10-Gb/s incoherent signal successfully transmitted over 20-km standard single-mode fiber without any dispersion compensation, but also retains the noise suppression after passing through a 0.2-nmbandwidth narrow optical filter. Two different line rates of 10.7 and 12.5 Gb/s are experimentally demonstrated, assuming 7% and 25% forward error correction, respectively. Also presented is the 10-Gb/s upstream transmission over a loopback configured network.Keywords-spectrum-slicing, incoherent light, optical acess network, wavelength-division-multiplexing.Wavelength-division-multiplexing (WDM) passive optical networks (PONs) have been considered as a promising solution to the last-mile technology to meet the soaring demand for bandwidth. However, one of the biggest challenges of deploying large-scale WDM-PON systems is still low-cost implementation and management of wavelength-selective light sources. The light sources operating at specific wavelengths make the optical network units all different from others, and thus do not allow the transponder manufacturers to enjoy the benefits of mass production. The service providers should also stock up all the different kinds of optical transmitters at their storehouse to be braced for any service failure caused by optical transmitter breakdown.Spectrum-sliced incoherent light (SSIL) sources are very attractive in this regard. A wideband amplified spontaneous emission (ASE) from an optical amplifier is spectrum-sliced into multiple channels by an waveguide grating router (WGR) to be used as optical sources for WDM PON instead of costly wavelength-specific light sources for each channel [1]. Therefore, SSIL sources can easily generate multiple wavelength channels from a single wideband optical amplifier without requiring any wavelength-selective lasers.The biggest concern about these incoherent light sources is large excess intensity noise (EIN) originated from the spontaneous-spontaneous beating between different wavelength components of the SSIL. This noise limits the maximum achievable signal-to-noise ratio (SNR) of the signal at the receiver, which can be expressed as B o /B e for unpolarized light, where B o is the optical bandwidth and B e is the electrical bandwidth [1].A couple of techniques have been proposed to overcome this SNR limitation: gain-saturated semiconductor optical amplifier (SOA) and feed-forward noise reduction [4], [7]. Nonetheless, the conventional approach to acco...
