Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

Abstract Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as
MoS 2, WS 2, MoSe 2, and WSe 2, have received extensive attention in the past decade due …

Nonlinear interactions between excitons strongly coupled to light are key for accessing
quantum many-body phenomena in polariton systems. Atomically-thin two-dimensional …

Controlling the interaction between light and matter at micro-and nano-scale can provide
new opportunities for modern optics and optoelectronics. An archetypical example is …

Highly nonlinear optical materials with strong effective photon-photon interactions are
required for ultrafast and quantum optical signal processing circuitry. Here we report strong …

The “marriage” of light (ie, photon) and matter (ie, exciton) in semiconductors leads to the
formation of hybrid quasiparticles called exciton polaritons with fascinating quantum …

Recently, it has been demonstrated that the absorption of moderately doped two-
dimensional semiconductors can be described in terms of exciton polarons. In this scenario …

Integrating two-dimensional materials into van der Waals heterostructures (vdWHs) is
considered to be an efficient strategy for multifunctional devices. Here, the m-GaS/n-MoTe 2 …

Loss-induced transparency (LIT), featuring the revival of optical intensity by adding loss, has
been demonstrated in classical optics. However, a fundamental question has remained …

Strong optical nonlinearities play a central role in realizing quantum photonic technologies.
Exciton-polaritons, which result from the hybridization of material excitations and cavity …
