“…Later, Yan et al demonstrated a slow-light silicon photonic-crystal waveguide with graphene microheater [124], as shown in Figure 3C, in which the tuning efficiency is about 1.07 nm/ mW and the rise time is about 750 ns. In 2017, the graphene microheater was also used for silicon nanobeam cavity [125] and the heating efficiency is as high as 1.5 nm/mW in experiment because of the shrunk heating volume. For these thermally tunable optical cavities with graphene nano-heaters, one can realize an efficient thermo-optic switch for a fixed wavelength around the resonance, which is useful for low power-consumption reconfigurable silicon photonics in the future.…”

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.

“…Under a 28 mW electrical power the resonant wavelength of the ring resonator has shifted by 2.9 nm, which led to a large modulation depth of 7 dB and a wide operation wavelength range of 6.2 nm [96]. Furthermore, graphene, as a transparent heater, has been integrated onto various silicon photonic crystal waveguides to demonstrate enhanced tuning efficiency and fast response time, which outperform the conventional metallic microheaters [115]. Yan et al experimentally presented an energy-efficient graphene microheater by incorporating a monolayer graphene onto a slow-light silicon photonic crystal waveguide.…”

AbstractThe burgeoning research into two-dimensional (2D) materials opens a door to novel photonic and optoelectronic devices utilizing their fascinating electronic and photonic properties in thin-layered architectures. The hybrid integration of 2D materials onto integrated optics platforms thus becomes a potential solution to tackle the bottlenecks of traditional optoelectronic devices. In this paper, we present the recent advances of hybrid integration of a wide range of 2D materials on integrated optics platforms for developing high-performance photodetectors, modulators, lasers, and nonlinear optics. Such hybrid integration enables fully functional on-chip devices to be readily accessible researchers and technology developers, becoming a potential candidate for next-generation photonics and optoelectronics industries.

A new class of hybrid systems that couple optical and mechanical nanoscale devices is under development. According to their interaction concepts, two groups of opto-mechanical systems are summarized as mechanically tunable and radiation pressure-driven optical resonators. On account of their high-quality factors and small mode volumes as well as good on-chip integrability with waveguides/circuits, photonic crystal (PhC) cavities have attracted great attention in sensing applications. Benefitting from the opto-mechanical interaction, a PhC cavity integrated opto-mechanical system provides an attractive platform for ultrasensitive sensors to detect displacement, mass, force, and acceleration. In this review, we introduce basic physical concepts of opto-mechanical PhC system and describe typical experimental systems for sensing applications. Opto-mechanical interaction-based PhC cavities offer unprecedented opportunities to develop lab-on-a-chip devices and witness a promising prospect to further manipulate light propagation in the nanophotonics.
