“…In order to compensate the drawbacks of silicon, currently siliconplus photonics has attracted intensive attention as a promising solution by introducing some other optoelectronic materials [11,12]. For example, people have tried to introduce various functional materials to work together with silicon, including metals [13], III-V semiconductors [14,15], germanium [16], two-dimensional (2D) materials [17][18][19][20], polymer [21,22], magnetic-optical materials [23], and liquid-crystals [24].…”

Abstract Silicon photonics is becoming more and more attractive in the applications of optical interconnections, optical computing, and optical sensing. Although various silicon photonic devices have been developed rapidly, it is still not easy to realize active photonic devices and circuits with silicon alone due to the intrinsic limitations of silicon. In recent years, two-dimensional (2D) materials have attracted extensive attentions due to their unique properties in electronics and photonics. 2D materials can be easily transferred onto silicon and thus provide a promising approach for realizing active photonic devices on silicon. In this paper, we give a review on recent progresses towards hybrid silicon photonics devices with 2D materials, including two parts. One is silicon-based photodetectors with 2D materials for the wavelength-bands from ultraviolet (UV) to mid-infrared (MIR). The other is silicon photonic switches/modulators with 2D materials, including high-speed electro-optical modulators, high-efficiency thermal-optical switches and low-threshold all-optical modulators, etc. These hybrid silicon photonic devices with 2D materials devices provide an alternative way for the realization of multifunctional silicon photonic integrated circuits in the future.

“…In particular, we focus on the on-chip mode-manipulation with two popular subwavelength photonic waveguide structures developed in the past years. One is silicon hybrid plasmonic waveguides (HPWGs) [6][7][8][9][10], which is fully SOI (silicon-on-insulator)-compatible and has strong field enhancement in the low-index nano-slot region as well as very strong polarization-dependence. Meanwhile, the propagation loss due to the metal absorption in HPWGs is at the order of 0.01 dB/μm, which is much lower than those traditional metal nanoplasmonic waveguides.…”

On-chip mode-manipulation is one of the most important physical fundamentals for many photonic integrated devices and circuits. In the past years, great progresses have been achieved on subwavelength silicon photonics for on-chip mode-manipulation by introducing special subwavelength photonic waveguides. Among them, there are two popular waveguide structures available. One is silicon hybrid plasmonic waveguides (HPWGs) and the other one is silicon subwavelength-structured waveguides (SSWGs). In this paper, we focus on subwavelength silicon photonic devices and the applications with the manipulation of the effective indices, the modal field profiles, the mode dispersion, as well as the birefringence. First, a review is given about subwavelength silicon photonics for the fundamental-mode manipulation, including high-performance polarization-handling devices, efficient mode converters for chip-fiber edge-coupling, and ultra-broadband power splitters. Second, a review is given about subwavelength silicon photonics for the higher-order-mode manipulation, including multimode converters, multimode waveguide bends, and multimode waveguide crossing. Finally, some emerging applications of subwavelength silicon photonics for on-chip mode-manipulation are discussed.

“…Owing to their unprecedented ability for highly efficient light transmission, hybrid plasmonics have been regarded as one of the key enabling technologies for the next-generation of integrated optical components and circuits [9]. Besides their outstanding guiding properties, HPWs also provide excellent compatibility with semiconductor materials, thereby potentially offering a promising platform that allows seamless integration with silicon photonics [10,11].…”

Hybrid plasmonic waveguides leveraging the coupling between dielectric modes and plasmon polaritons have emerged as a major focus of research attention during the past decade. A feasible way for constructing practical hybrid plasmonic structures is to integrate metallic configurations with silicon-on-insulator waveguiding platforms. Here we report a transformative high-performance silicon-based hybrid plasmonic waveguide that consists of a silicon nano-rib loaded with a metallic nanowire. A deep-subwavelength mode area (λ 2 ∕4.5 × 10 5 − λ 2 ∕7 × 10 3), in conjunction with a reasonable propagation distance (2.2-60.2 μm), is achievable at a telecommunication wavelength of 1.55 μm. Such a nano-rib-based waveguide outperforms its conventional hybrid and plasmonic waveguiding counterparts, demonstrating tighter optical confinement for similar propagation distances and a significantly enhanced figure of merit. The guiding properties of the fundamental mode are also quite robust against possible fabrication imperfections. Due to the strong confinement capability, our proposed hybrid configuration features ultralow waveguide cross talk and enables submicron bends with moderate attenuation as well. The outstanding optical performance renders such waveguides as promising building blocks for ultracompact passive and active silicon-based integrated photonic components.
