Title: Silicon-Phosphorene Nanocavity-Enhanced Optical Emission at Telecommunications Wavelengths

Abstract

Generating and amplifying light in silicon (Si) continues to attract significant attention due to the possibility of integrating optical and electronic components in a single material platform. Unfortunately, silicon is an indirect band gap material and therefore an inefficient emitter of light. With the rise of integrated photonics, the search for silicon-based light sources has evolved from a scientific quest to a major technological bottleneck for scalable, CMOS-compatible, light sources. Recently, emerging two-dimensional materials have opened the prospect of tailoring material properties based on atomic layers. Few-layer phosphorene, which is isolated through exfoliation from black phosphorus (BP), is a great candidate to partner with silicon due to its layer-tunable direct band gap in the near-infrared where silicon is transparent. Here we demonstrate a hybrid silicon optical emitter composed of few-layer phosphorene nanomaterial flakes coupled to silicon photonic crystal resonators. We show single-mode emission in the telecommunications band of 1.55 μm ($$E_g$$ = 0.8 eV) under continuous wave optical excitation at room temperature. The solution-processed few-layer BP flakes enable tunable emission across a broad range of wavelengths and the simultaneous creation of multiple devices. Our work highlights the versatility of the Si-BP material platform for creating optically active devices in integrated silicon chips.

Electronic energy loss spectra from mono-layer to few layers of phosphorene

Journal Article Mohan, Brij ; Thakur, Rajesh ; Ahluwalia, P. K. - AIP Conference Proceedings

Using first principles calculations, electronic and optical properties of few-layers phosphorene has been investigated. Electronic band structure show a moderate band gap of 0.9 eV in monolayer phosphorene which decreases with increasing number of layers. Optical properties of few-layers of phosphorene in infrared and visible region shows tunability with number of layers. Electron energy loss function has been plotted and huge red shift in plasmonic behaviours is found. These tunable electronic and optical properties of few-layers of phosphorene can be useful for the applications of optoelectronic devices.

Epitaxial Synthesis of Blue Phosphorene

Journal Article Zhang, Wei ; Enriquez, Hanna ; Tong, Yongfeng ; ... - Small

Phosphorene is a new 2D material composed of a single or few atomic layers of black phosphorus. Phosphorene has both an intrinsic tunable direct bandgap and high carrier mobility values, which make it suitable for a large variety of optical and electronic devices. However, the synthesis of single-layer phosphorene is a major challenge. The standard procedure to obtain phosphorene is by exfoliation. More recently, the epitaxial growth of single-layer phosphorene on Au(111) was investigated by molecular beam epitaxy and the obtained structure described as a blue phosphorene sheet. In the present study, large areas of high-quality monolayer phosphorene, with amore »« less

Stable aqueous dispersions of optically and electronically active phosphorene

Journal Article Kang, Joohoon ; Wells, Spencer A. ; Wood, Joshua D. ; ... - Proceedings of the National Academy of Sciences of the United States of America

Understanding and exploiting the remarkable optical and electronic properties of phosphorene require mass production methods that avoid chemical degradation. Although solution-based strategies have been developed for scalable exfoliation of black phosphorus, these techniques have thus far used anhydrous organic solvents in an effort to minimize exposure to known oxidants, but at the cost of limited exfoliation yield and flake size distribution. In this work, we present an alternative phosphorene production method based on surfactant-assisted exfoliation and postprocessing of black phosphorus in deoxygenated water. From comprehensive microscopic and spectroscopic analysis, this approach is shown to yield phosphorene dispersions that are stable,more »« less

Near infrared emission of TbAG:Ce{sup 3+},Yb{sup 3+} phosphor for solar cell applications

Luminescent materials doped with rare earth ions are used for many devices such as optical amplifiers in telecommunication, phosphors for white light emitting diodes (LEDs), displays, and so on. Recently, they also have attracted a great interest for photovoltaic applications to improve solar cell efficiency by modifying solar spectrum. Crystal silicon (c-Si) solar cells most effectively convert photons of energy close to the semiconductor band gap. The mis-match between the incident solar spectrum and the spectral response of solar cells is one of the main reasons to limit the cell efficiency. The efficiency limit of the c-Si has been estimatedmore »« less

Cavity Engineering of Photon–Phonon Interactions in Si Nanocavities

Journal Article Agarwal, Daksh ; Yoo, Jinkyoung ; Pan, Anlian ; ... - Nano Letters

The ever-increasing demand for faster, smaller, and energy-efficient devices has pushed the frontiers of research toward silicon photonics to meet the challenges for fabricating the next generation of computing systems. In order to design new devices at the nanoscale, it is important to understand and be able to control material properties, which may differ significantly from their bulk counterparts. Here, we demonstrate very large tunability of phonon–photon interactions in Si nanowire cavities by engineering the cavity mode at the emission wavelength. Raman scattering measurements performed to quantify these interactions reveal that the anti-Stokes to Stokes scattering ratio can vary frommore »« less
