“…For example, a 2D semiconductor nonlinear modulator with ultrafast response time has been demonstrated [165], as illustrated in Figure 8B. These plasmonic structures enhance the light-matter interaction dramatically and bring new opportunities for all-optical modulation, with low power consumption and insertion loss [167,169]. In addition, the relaxation time of surface plasmons is usually on the order of 10 fs, which offers opportunities of ultrafast modulation with 2D materials.…”

Abstract Optical modulation technique plays a crucial role in photonics technologies, and there is an ever-increasing demand for broadband and ultrafast optical modulation in the era of artificial intelligence. All-optical modulation is known to be able to operate in an ultrafast way and has a broadband response, showing great potential in applications for ultrafast information processing and photonic computing. Two-dimensional (2D) materials with exotic optoelectronic properties bring tremendous new opportunities for all-optical modulators with excellent performance, which have attracted lots of attention recently. In this review, we cover the state-of-art all-optical modulation based on 2D materials, including graphene, transitional metal dichalcogenides, phosphorus, and other novel 2D materials. We present the operations mechanism of different types of all-optical modulators with various configurations, such as fiber-integrated and free-space ones. We also discuss the challenges and opportunities faced by all-optical modulation, as well as offer some future perspectives for the development of all-optical modulation based on 2D materials.

“…Besides graphene, TMDCs also exhibit impressive optoelectronic properties including large third-order NLO susceptibilities and strong light-matter interaction [191,192]. Most recently, Klein et al [190] proposed a plasmonic modulator based on WSe2 monolayer integrated on top of a metallic waveguide. As shown in Figure 7C, WSe2 monolayer is electrically isolated from the metal by encapsulating with hBN.…”

Abstract Due to their novel electronic and optical properties, atomically thin layered two-dimensional (2D) materials are becoming promising to realize novel functional optoelectronic devices including photodetectors, modulators, and lasers. However, light–matter interactions in 2D materials are often weak because of the atomic-scale thickness, thus limiting the performances of these devices. Metallic nanostructures supporting surface plasmon polaritons show strong ability to concentrate light within subwavelength region, opening thereby new avenues for strengthening the light–matter interactions and miniaturizing the devices. This review starts to present how to use metallic nanostructures to enhance light–matter interactions in 2D materials, mainly focusing on photoluminescence, Raman scattering, and nonlinearities of 2D materials. In addition, an overview of ultraconfined acoustic-like plasmons in hybrid graphene–metal structures is given, discussing the nonlocal response and quantum mechanical features of the graphene plasmons and metals. Then, the review summarizes the latest development of 2D material–based optoelectronic devices integrated with plasmonic nanostructures. Both off-chip and on-chip devices including modulators and photodetectors are discussed. The potentials of hybrid 2D materials plasmonic optoelectronic devices are finally summarized, giving the future research directions for applications in optical interconnects and optical communications.

“…This waveguide-resonator system enables high-contrast modulation, allowing phase shifting up to 180 • , with bandwidths up to 100 GHz, and speeds in the order of 0.2 ns. Figure 3e, on the other hand, illustrates a 2D semiconductor-plasmonic heterostructure for an ultra-low switching energy plasmonic modulator [145]. This latter structure couples an SPP mode, propagating along the plasmonic waveguide, with excitons in the two-dimensional hBN-WSe 2 -hBN (hexagonal Boron Nitride-Tungsten Diselenide-hexagonal Boron Nitride) semiconductor.…”

Plasmonic materials, when properly illuminated with visible or near-infrared wavelengths, exhibit unique and interesting features that can be exploited for tailoring and tuning the light radiation and propagation properties at nanoscale dimensions. A variety of plasmonic heterostructures have been demonstrated for optical-signal filtering, transmission, detection, transportation, and modulation. In this review, state-of-the-art plasmonic structures used for telecommunications applications are summarized. In doing so, we discuss their distinctive roles on multiple approaches including beam steering, guiding, filtering, modulation, switching, and detection, which are all of prime importance for the development of the sixth generation (6G) cellular networks.
