A Thresholdless Tunable Raman Nanolaser using a ZnO–Graphene Superlattice

Abstract

Nanolasers based on surface plasmon opens up new platform for advanced nanophotonics technologies. [1][2][3][4][5][6] As Raman scattering process convert pump laser into new frequencies, so development of Raman nanolaser may allows for tunable nanolasers and boost the development of innovative nanophotonics technology. The Raman conversion for conventional Raman laser is intrinsically challenging as high intensities of the pump laser are required to drive the nonlinear effect. In recent years, miniaturization of Raman silicon laser has been successfully achieved with the assistance of reverse-biased p-i-n diode at centimeter size or photonics-crystal with high-quality-factor nanocavity at micrometer size. [7][8][9] However, for applications such as high-resolution medical imagings or on-chip optical communications, 'ultimate' nanolasers with scalable, thresholdless,

Biofabrication of Zinc Oxide Nanoparticles With Syzygium aromaticum Flower Buds Extract and Finding Its Novel Application in Controlling the Growth and Mycotoxins of Fusarium graminearum

“…Which include antimicrobial agents, nanobiosensors, food packaging material, catalysts, etc. (Zhu and Deng, 2017; Zhu H. et al, 2017; Zhu L. et al, 2017; Siddaiah et al, 2018; Kalagatur et al, 2018a; Gunti et al, 2019). As of now, the contagious pervasion and mycotoxin pollution of nourishment is one of the principals stresses of agribusiness and sustenance industry (Adeyeye, 2016).…”

Onset of Lasing in Small Devices: The Identification of the First Threshold through Autocorrelation Resonance

“…Since, in addition, the aim is to move toward continuously pumped devices and—as reviewed in ref. [], recent work has shown considerable progress in that direction—this scheme does not offer a general‐purpose solution for threshold identification. The strong push for a correct identification of threshold in very small devices, in support of the claim of laser emission, justifies the recent directed efforts…”

Plasmonics of 2D Nanomaterials: Properties and Applications

“…Furthermore, the hybridization of 2D materials and metal nanomaterials attracts growing interest, since the metallic plasmons interact strongly with excitons and 2D material plasmons. 2D materials hybrid structures such as ZnO/graphene or LTMDCs/photonic crystal compound stacks show potential to be photodiode for photocurrent generation or photodetection, furthermore, latest SPs induced nanolasers methods attract great interest, and many groups are searching for a way to create ultra‐small, tunable, thresholdless and efficient laser sources which can be promising for high‐resolution medical imaging and on‐chip optical communications . However, due to the different atomic arrangements and bonding types between metal and 2D materials, the interfacial condition are hard to be controlled.…”
