Transverse-electric surface plasmon polaritons in periodically modulated graphene
Zeeshan Ahmad, Sang Soon Oh, Egor A. Muljarov
Transverse-electric (TE) surface plasmon polaritons are unique eigenmodes of a homogeneous graphene layer that are tunable with the chemical potential and temperature. However, as…
Sign freedom of non-Abelian topological charges in phononic and photonic topological insulators
Haedong Park, Sang Soon Oh
The topological nature of nodal lines in a three-band system can be described by non-Abelian topological charges called quaternion numbers. Due to the gauge freedom of the eigensta…
Self-induced ultrafast electron-hole plasma temperature oscillations in nanowire lasers
Andreas Thurn, Jochen Bissinger, Stefan Meinecke +6
Nanowire lasers can be monolithically and site-selectively integrated onto silicon photonic circuits. To assess their full potential for ultrafast opto-electronic devices, a detail…
Extended frequency range of transverse-electric surface plasmon polaritons in graphene
Zeeshan Ahmad, Egor A. Muljarov, Sang Soon Oh
The dispersion relation of surface plasmon polaritons in graphene that includes optical losses is often obtained for complex wave vectors while the frequencies are assumed to be re…
The Nature of Topological Protection in Spin and Valley Hall Insulators
Matthias Saba, Stephan Wong, Mathew Elman +2
Recent interest in optical analogues to the quantum spin Hall and quantum valley Hall effects is driven by the promise to establish topologically protected photonic edge modes at t…
Reading the orbital angular momentum of light using plasmonic nanoantennas
R. M. Kerber, J. M. Fitzgerald, D. E. Reiter +2
Orbital angular momentum of light has recently been recognized as a new degree of freedom to encode information in quantum communication using light pulses. Methods to extract this…
