Herein, an attention-grabbing and up-to-date review related to major multiplexing techniques is presented which includes wavelength division multiplexing (WDM), polarization division multiplexing (PDM), space division multiplexing (SDM), mode division multiplexing (MDM) and orbital angular momentum multiplexing (OAMM). Multiplexing is a mechanism by which multiple signals are combined into a shared channel used to showcase the maximum capacity of the optical links. However, it is critical to develop hybrid multiplexing methods to allow enhanced channel numbers. In this review, we have also included hybrid multiplexing techniques such as WDM-PDM, WDM-MDM and PDM-MDM. It is probable to attain N×M channels by utilizing N wavelengths and M guided-modes by simply utilizing hybrid WDM-MDM (de)multiplexers. To the best of our knowledge, this review paper is one of its kind which has highlighted the most prominent and recent signs of progress in multiplexing techniques in one place.

“…They have great application potential in many research and technical fields such as high-performance computer, optical communication, quantum information and artificial intelligence, due to the broad bandwidth and large information capacity. There are various works [4][5][6][7][8][9][10][11][12] reported in recent years, but all of them are single devices with different realization schemes and different structure types or even different materials. No effective method has been found to design On-chip cascaded bandpass filter and wavelength router directly, which seriously restricts the development of integration for two or more nanophotonic devices.…”

“…Besides the fore-end device, in the practical application of nanophotonic chip, devices are required to transmit different information into different channels, in which wavelength router is an essential component. Wavelength routers based on photonic crystal [10] and grating [11] have broad operation band but large size, which restricts the improvement of integration density when cascading with other nanophotonic devices. Surface plasmon polariton can be applied to design smaller wavelength router, however, it suffers from loss [8,16].…”

Cascaded nanophotonic devices play a vital role in all-optical connection, all-optical computation and all-optical network. However, there is almost no effective method for the direct design of on-chip cascaded nanophotonic devices, since current study of nanophotonic devices mostly focuses on single device. Here, on-chip cascaded nanophotonic devices are designed based on an intelligent algorithm by combining genetic algorithm, simulated annealing algorithm and finite element method for the first time, and verified experimentally by using silicon-based planar structures. The cascaded devices consist of a bandpass filter and a wavelength router operating in optical communication range. The operation bandwidth of the bandpass filter is 408 nm with transmission more than 80%, within which the communication wavelengths of 1,300 nm and 1,550 nm are routed into different output ports through the wavelength router component. The footprint is only 3.62 μm 2 for the bandpass filter and only 2.56 μm 2 for the wavelength router, which are easy for integration with planar structures and ultrasmall size. This work provides a highly-efficient scheme for the realization of on-chip cascaded nanophotonic devices on the same chip, and lays a foundation for the realization of photonic chip based on intelligent algorithm.

“…Most previous researches were concentrated on the near infrared (NIR) bands (1300 -1700 nm), especially at 1310 nm, 1490 nm, and 1550 nm, which are widely used in the fiber-to-the-X (FTTX) systems. The schemes mainly contain grating couplers [2,3], directional couplers (DCs) [4,5], Photonic crystals [6,7], multimode interference (MMI) couplers [8,9], Mach-Zehnder interferometers (MZIs) [10], inversely designed metamaterials [11], and so on. In response to the rapidly growing demand of networks, it is extremely necessary to exploit a new telecommunication window.…”

A high contrast and compact wavelength diplexer is presented for conventional 1550 nm and emerging 2000 nm based on a subwavelength-grating (SWG) coupler. The SWG silicon waveguide thoroughly blocks the light propagation around 1550 nm but fully supports 2000 nm (extinction ratio: 43.11 dB). This grating type anisotropic metamaterial not only efficiently reduces the coupling length but also expands the operational bandwidth. Simulated by 3D finite-difference time-domain method, the proposed diplexer possesses remarkably low insertion loss and high contrast of 25.24 (31.7) dB at 1550 (2000) nm. The operational bandwidth of 200 (108) nm is achieved with contrast over 15 dB and insertion loss below 0.22 dB. The footprint of diplexer is only 5.27 μm × 11.85 μm. Moreover, such design has the scalability by simply tuning the geometrical parameters of SWG.
