  1. 1. Topological Photonic Lattices

    University essay from KTH/Tillämpad fysik

    Author : Zesheng Xu; [2022]
    Keywords : Topological photonics; Integrated photonics; Condensed matter physics physics; Optics; Topologisk fotonik; integrerad fotonik; fysik för kondenserad materia; Optik;

    Abstract : Topological Photonics is a rapidly growing field which explores the ideas of topological invariants adapted from condensed matter physics to optical systems. Thanks to integrated photonics platforms, the evolution of light in nanoscale photonic lattices can enable direct measurement of topological properties of the band-structure. READ MORE

  3. 2. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Nathan Ullberg; [2020]
    Keywords : backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

    Abstract : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.

  6. 5. Absorption of light through isolated and coupled resonances in horizontal InP nanowire arrays

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Ali Hosseinnia; [2015]
    Keywords : Coupling; Optical resonances; Horizontal nanowires; Periodic Array; Indium Phosphide; Finite Element Method; Scattering Matrix Method; Eigen function method; Mie Theory; Scattering; Absorption; Nano-Optics; Nanowire; Physics and Astronomy;

    Abstract : We have studied the interaction of light with two types of closely related nanostructures: a single horizontal InP nanowire and an infinite periodic array of such nanowires. The study has been done theoretically by calculating the absorption cross section of the nanowires via a semi analytical method, the Mie theory, and two numerical methods, the scattering matrix method (SMM) and the finite element method (FEM) to perform electromagnetic modeling.
