“…As demonstrated before, the mode (de)multiplexer based on cascaded ADCs could work very well over a broad bandwidth [82]. Therefore, it is promising to develop hybrid MDM-WDM (de)multiplexers by integrating an ADC-based mode (de)multiplexer [28] and AWG-based WDM devices.…”

“…This helps reduce the device footprint greatly and also simplifies the configuration significantly. As the four-channel mode (de)multiplexer has been developed very well for TM polarization [82], this hybrid MDM-WDM (de)multiplexer was also designed for TM polarization as an example. It is important to achieve an MRR with a large FSR, which is determined by the cavity length given by L cav = 2πR.…”

“…An MRR-based hybrid MDM-WDM (de)multiplexer for TE polarization has also been demonstrated recently. This hybrid MDM-WDM (de)multiplexer consists of an M -channel mode (de)multiplexer based on dual-core adiabatic tapers and an N -channel MRR-based WDM filter with box-like responses [82], as shown in Figure 7. The mode (de)multiplexer has four mode-channels of TE polarization and is realized by using the design with dual-core adiabatic tapers.…”

A review is given on the recent progress of silicon-based on-chip hybrid multiplexers, which are the key elements to enable more than one (de)multiplexing techniques simultaneously, including wavelengthdivision-multiplexing (WDM), polarization-division-multiplexing (PDM), and mode-division-multiplexing (MDM). This helps enhance the link capacity of optical interconnects multiplexed with many channels. The first part gives a review on the recent developed silicon-based hybrid WDM-PDM (de)multiplexers enabling WDM and PDM simultaneously, which helps achieve 2N channels by introducing N wavelengths and dual polarizations. The recent progress of silicon-based hybrid WDM-MDM (de)multiplexers developed is reviewed in the second part. With the hybrid WDM-MDM (de)multiplexers, one can achieve N ×M channels by using N wavelengths and M guided-modes. Finally, the silicon-based hybrid MDM-PDM (de)multiplexers are presented as the key to enhance the link capacity for a single wavelength carrier.

“…As with any maturing technology, WDM too had a lot of challenges to be tackled as it progresses. For example, [13] discusses a hybrid multiplexer which can be used for WDM and MDM. Also WDM have found applications beyond communication, which also brings about additional challenges.…”

Optical multiplexing is the art of combining multiple optical signals into one to make full use of the immense bandwidth potential of an optical channel. It can perform additional roles like providing redundancy, supporting advanced topologies, reducing hardware and cost, etc. The idea is to divide the huge bandwidth of optical fiber into individual channels of lower bandwidth, so that multiple access with lower-speed electronics is achieved. This chapter focuses on one of the most common and important optical multiplexing techniques, wavelength division multiplexing (WDM). The chapter begins with a quick historical account of the origin of optical communication and its exponential growth following the invention of erbium-doped fiber amplifier (EDFA) leading to the widespread adoption of WDM. Alternate multiplexing schemes are also briefly discussed, including time-division multiplexing (TDM), space-division multiplexing (SDM), etc. A typical WDM link and its components are then discussed with special focus on WDM Mux/demultiplexer (DeMux). Further, certain challenges in this field are addressed along with some potential solutions. The chapter concludes by highlighting some features and limitations of optically multiplexed WDM systems.

“…But the lengths of the reported TDC-based mode (de)multiplexers are conventionally very long. Thus, it is challenging to achieve a mode (de)multiplexer with compact footprint, low crosstalk, broad bandwidth, and excellent scalability, especially when mode (de)multiplexers are used to construct hybrid (de)multiplexers or switches [28][29][30]. In this paper, we propose a design of a silicon mode (de)multiplexer based on cascaded particle-swarm-optimized counter-tapered couplers.…”
