TL;DR: In this article, the authors survey the recent advances in nonlinear optics and the applications of two-dimensional (2D) materials and highlight a few representative current applications of 2D materials to photonic and optoelectronic devices.

TL;DR: A novel ultrathin bismuthene-based sensing platform for microRNA (miRNA)-specific detection that even discriminates single-base mismatches and sensitively detect miRNA molecules for early cancer is developed.

TL;DR: In this paper, several layers of germanene were prepared with Dirac electronic characteristics and its morphology, band structure, carrier dynamics, and nonlinear optical properties were systematically investigated, and it was surprisingly found that Germanene has a fast carrier-relaxation time comparable to that of graphene and a relatively large nonlinear absorption coefficient, which is an order of magnitude higher than that of GAs in the near-infrared wavelength range.

TL;DR: In this paper, the Pauli blocking limit and optical limiting threshold have been modified following silver-nanoparticle decoration of functionalized hydrogen induced exfoliated graphene and the observed results have been explained by modified band structure of graphene in the presence of silver nanoparticles and their localized surface plasmon resonances.

TL;DR: Two photon absorption (2PA) cross sections of two quasi-octupolar molecules (E, E, E )-2,4,6-tris [2-(4- N, N -diphenylaminophenyl)vinyl]pyridine (DPATSP) and (2, 4, 6-trithm((E )-4-(diphenyl)styryl)-1-methylpyridinium-1-ium iodide, DPATSP-Me) have been estimated as discussed by the authors.
