“…In contrast, fibre communications are increasingly targeting multimode operation in conjunction with WDM to further scale the communication bandwidth transmitted per fibre 3 . Multimode communications in fibres have been demonstrated with space-division multiplexing in multi-core fibres [4][5][6][7][8] or mode-division multiplexing (MDM) in few-mode fibres [9][10][11][12][13][14][15][16][17] and have exploited each spatial mode as an independent channel. It is similarly of interest to attempt to incorporate the spatial-mode-parallelism degree of freedom into complex photonic-integrated circuits to introduce additional functionality and provide potential performance gains.…”

Significant effort in optical-fibre research has been put in recent years into realizing mode-division multiplexing (MDM) in conjunction with wavelength-division multiplexing (WDM) to enable further scaling of the communication bandwidth per fibre. In contrast, almost all integrated photonics operate exclusively in the single-mode regime. MDM is rarely considered for integrated photonics because of the difficulty in coupling selectively to high-order modes, which usually results in high inter-modal crosstalk. Here we show the first microring-based demonstration of on-chip WDM-compatible mode-division multiplexing with low modal crosstalk and loss. Our approach can potentially increase the aggregate data rate by many times for on-chip ultrahigh bandwidth communications.

“…Spatial Division Multiplexing (SDM) [44] is another approach investigated that has recently being advanced by the research community, albeit being proposed many years ago. This approach can further address this capacity crunch by using a MM (few moded) fiber instead of a SM fiber, and using its spatial modes [45][46][47][48] and even high order orbital angular momentum modes in specialty fiber [49] as an additional degree of freedom to increase the number of data channels. Another SDM approach is the use of multicore fibers [50][51][52], here the spatial multiplexing is done by using the uncoupled cores of a multicore fiber as independent data channels.…”

Multimode optical fibers have been primarily (and almost solely) used as "light pipes" in short distance telecommunications and in remote and astronomical spectroscopy. The modal properties of the multimode waveguides are rarely exploited and mostly discussed in the context of guiding light. Until recently, most photonic applications in the applied sciences have arisen from developments in telecommunications. However, the photonic lantern is one of several devices that arose to solve problems in astrophotonics and space photonics. Interestingly, these devices are now being explored for use in telecommunications and are likely to find commercial use in the next few years, particularly in the development of compact spectrographs. Photonic lanterns allow for a low-loss transformation of a multimode waveguide into a discrete number of single-mode waveguides and vice versa, thus enabling the use of single-mode photonic technologies in multimode systems. In this review, we will discuss the theory and function of the photonic lantern, along with several different variants of the technology. We will also discuss some of its applications in more detail. Furthermore, we foreshadow future applications of this technology to the field of nanophotonics.
