Non-Hermitian dispersion sign reversal of radiative resonances in two dimensions
R. Binder, J. S. Schaibley, N. H. Kwong
In a recent publication [Wurdack et al., Nat. Comm. 14:1026 (2023)], it was shown that in microcavities containing atomically thin semiconductors non-Hermitian quantum mechanics ca…
Gapless fluctuations and exceptional points in semiconductor lasers
N. H. Kwong, M. Em. Spotnitz, R. Binder
We analyze the spectrum of spatially uniform, single-particle fluctuation modes in the linear electromagnetic response of a semiconductor laser. We show that if the decay rate of t…
Theory of optically controlled anisotropic polariton transport in semiconductor double microcavities
S. M. H. Luk, P. Lewandowski, N. H. Kwong +8
Exciton polaritons in semiconductor microcavities exhibit many fundamental physical effects, with some of them amenable to being controlled by external fields. The polariton transp…
Transverse optical instability patterns in semiconductor microcavities: polariton scattering and low-intensity all-optical switching
M. H. Luk, Y. C. Tse, N. H. Kwong +4
We present a detailed theoretical study of transverse exciton-polariton patterns in semiconductor quantum-well microcavities. These patterns are initiated by directional instabilit…
All-optical switching in planar semiconductor microcavities
S. Schumacher, N. H. Kwong, R. Binder +1
Using a microscopic many-particle theory, we propose all-optical switching in planar semiconductor microcavities where a weak beam switches a stronger signal. Based on four-wave-mi…
Polariton amplification in a multiple-quantum-well resonant photonic crystal
S. Schumacher, N. H. Kwong, R. Binder
Based on a microscopic many-particle theory we study the amplification of polaritons in a multiple-quantum-well resonant photonic crystal. For the Bragg-spaced multiple quantum wel…
