“…Hence, each transmitter has to be manufactured to a high specification and close temperature control is required to eliminate the potential for temperature induced wavelength drift. The combination of these requirements results in transmitters that are expensive, requires significant cooling powers, and gives systems operators the additional burden of maintaining an 0733-8724 © 2013 IEEE Spectrum sliced WDM-PON architectures using reflective semiconductor optical amplifiers (RSOAs) as colorless transmitters at each end node can potentially meet the demands of an aircraft network [7], [8] in a more cost effective manner. We analyze the performance of such a network using two different RSOAs-first using a standard commercially available RSOA [9] and second an Aluminum containing quaternarybased RSOA designed to operate at elevated temperatures.…”

Growth in demand for bandwidth within avionic systems has renewed interest in wavelength division multiplexing (WDM) topologies. Within an Avionics context, systems are specified for operation from -55 • C to 125 • C. This increased operational temperature range exceeds the capability of commercial off the shelf components. Here, we have investigated the design and operation of a dense WDM network over an extended temperature range. The implementation uses spectrum sliced seed sources in combination with reflective semiconductor optical amplifier (RSOA) end nodes. We report on the performance of a single polarization ridge waveguide RSOA with an Al containing quaternary active region. Two different designs of RSOA have been evaluated: a standard bulk heterostructure device and the single polarization ridge waveguide device design for high temperature operation. It has been shown that a SS-WDM network can be implemented using the RWG-RSOA and maintain a BER of 10 −9 at 75 • C allowing for 6 dB excess loss to account for component and connector aging. This offers an extension of at least 20 • C when compared to the standard bulk active RSOA. In addition, a novel passive cooling method, devised to compensate for short term excursions outside the maximum thermal operating envelope, has been investigated. This technique uses a phase change material as a passive, cooling mechanism. The performance of this method is contrasted against a thermoelectric cooler considering the influence of power consumption on fuel requirements for a Boeing 737-800.Index Terms-Dense wavelength division multiplexing (DWDM), energy efficiency, optical amplifiers, semiconductor optical amplifiers (SOAs).

“…Although a variety of creative schemes and devices have been investigated [16,17], from a performance standpoint, the availability of an ONU with a wavelength tunable laser as the transmitter will provide superior signal quality, reach, and stability, with the wavelength of each ONU tuned to the appropriate upstream channel. The underlying issue has been the cost of the widely tunable lasers being unable to reach the cost points required for adoption in access networks.…”

“…While offering the same functionalities of tunable lasers, self-seeding brings advantages, such as the self-tunability, a faster tuning time (compared to conventional tunable lasers) at a significantly reduced cost and no need of calibration. In addition, self-seeded transmitters do not require external seeding sources, which represent potentially a single point of failure for the overall network [4], and allow network design free from impairments due to in-band crosstalk [5]. Another key requirement for future WDM-PONs is the reduction of power consumption.…”

We present for the first time an experimental characterization of uncooled and polarization-insensitive operations of directly modulated self-seeded Fabry-Pérot laser diodes (FP-LDs) for wavelength division multiplexed passive optical networks (WDM-PONs). Polarization-insensitive operations are achieved through the combination of nonreciprocal optical elements placed both at the FP-LD and the WDM distribution node, which is placed within the PON. Compared to self-seeded reflective semiconductor optical amplifiers, the FP-LDs show narrower emission linewidth, resulting in improved resilience to chromatic dispersion. The 1.25-Gb/s WDM system operation is assessed on 32 channels in the C-band over a 100-GHz grid and in a wide range of ambient temperature (0°C-60°C). The results shown in this letter promote the self-seeded uncooled FP-LDs to a potential candidate for WDM-PON deployments.Index Terms-Fabry-Pérot laser, wavelength division multiplexed passive optical networks (WDM-PONs).
