Over the past decade, research on atomically thin two-dimensional (2D) transition metal
dichalcogenides (TMDs) has expanded rapidly due to their unique properties such as high …

Strong coupling is a distinct light–matter interaction regime, in which the interaction is
manifested in coherent oscillations of energy between matter and a photonic subsystem …

Optical parametric amplification is a second-order nonlinear process whereby an optical
signal is amplified by a pump via the generation of an idler field. This mechanism is …

Despite the potential of graphene for building a variety of quantum photonic devices, its
centrosymmetric nature forbids the observation of second harmonic generation (SHG) for …

Spin-forbidden excitons in monolayer transition metal dichalcogenides are optically inactive
at room temperature. Probing and manipulating these dark excitons are essential for …

Abstract 2D semiconductors, such as molybdenum disulfide (MoS2), have attracted
tremendous attention in constructing advanced monolithic integrated circuits (ICs) for future …

Nonlinear optical processes lie at the heart of frequency tunable coherent light sources,
including entangled photon sources and squeezed states of light, and they have become …

This work presents the dynamic response based on non-linear material (NLM) for the
electrical and optical analogy of the full optical oscillator. The full optical oscillator based on …

Time-varying metasurfaces are emerging as a powerful instrument for the dynamical control
of the electromagnetic properties of a propagating wave. Here we demonstrate an efficient …

Abstract Second-order (χ (2)) optical nonlinearity is one of the most common mechanisms for
