“…Wavelength converters, apart from merely converting a signal from one wavelength band to another, can be used for many important functions in nonlinear-optical signal processing [1][2][3][4][5]. In recent years, the interest in growing the transmission link capacity of both classical and quantum communications by space-division multiplexing (SDM) in fewmode fibers (FMFs) has brought attention to the spatial-mode properties of wavelength converters.…”

In the absence of quantum repeaters, the only way to increase the quantum communication capacity at a given reach is to employ more modes for encoding and transmitting information. While frequency, temporal, and polarization modes have already been exploited for this purpose, the use of many spatial modes over long distances has only recently become possible owing to the development of low-loss few-mode fibers (FMFs).We will discuss the development of two key enablers of quantum communication over FMF spatial modes: 1) spatiallyentangled photon-pair generator and 2) dynamically-reconfigurable spatial-mode de-multiplexer that can perform projective measurements alternating between two sets of mutually unbiased bases in a given spatial mode space. Both devices are based on the spatial-mode-selective quantum frequency conversion process, implemented in either χ (2) (multimode LiNbO3 waveguide) or χ (3) (custom-made FMF) nonlinear medium.

“…An experimental demonstration of this system concept was given in a triple-band Whole band wavelength conversion can play other roles in future optical networks by providing advanced functionality. Such functionality can include amplification [115], MB protection and bidirectional transmission [116], and transmission performance improvement by equalizing the signal quality by wavelength-band switching within a multispan transmission system [117].…”

In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most cost-efficient and thus the main driver for capacity increase for decades. As a result, the development of optical transport systems has been focused on the C-and L-bands, where silica optical fiber exhibits the lowest attenuation, and erbium-doped fiber amplifiers provide an efficient solution to compensate for the optical loss. With a gradual maturity in the SE growth, however, the extension of the optical bandwidth beyond the C + L-band is expected to play a significant role in future capacity upgrades of optical networks and, thus, attract increasing research interests. In this article, we discuss the merits and challenges of ultrawideband optical transport systems and networks beyond conventional bands. KEYWORDS | Optical communication; optical network and switching; optical transceiver (TRx); Raman amplification; ultrawideband (UWB) transmission; wavelength conversion; wavelength-division multiplexing (WDM).
