We present a review of theoretical and experimental aspects of multiphoton quantum optics.
Multiphoton processes occur and are important for many aspects of matter–radiation …

Electromagnetically induced transparency (EIT) stems from a quantum system, where an
opaque atomic medium appears the narrow transparent state within a wide absorption area …

Metamaterial analogues of electromagnetically induced transparency (EIT) have been
intensively studied and widely employed for slow light and enhanced nonlinear effects. In …

We analyze the electromagnetically induced transparency (EIT) in V-, Λ-, and cascade-type
schemes in a time-dependent way via the Schrödinger-Maxwell formalism. We derive …

We perform a time-dependent analysis of four-wave mixing (FWM) in a double-Λ system in
an ultraslow-propagation regime and obtain the analytical expressions of pulsed probe …

Optoelectronic terahertz modulators, operated by actively tuning metamaterial, plasmonic
resonator structures, have helped to unlock a myriad of terahertz applications, ranging from …

We study optical bistability (OB) behavior based on intersubband transitions in asymmetric
double quantum wells (QWs) where tunneling-induced quantum inference can be observed …

We analyze hybrid absorptive-dispersive optical bistability (OB) and multistability (OM)
behavior in a generic N-type atomic system driven by a degenerate probe field and a …

We investigate the interaction of laser pulses carrying orbital angular momentum (OAM) with
a symmetry-broken ladder-type quantum coupling scheme involving three internal states. A …

We analyze a lifetime-broadened four-state, ladder-type four-wave mixing (FWM) scheme in
the context of optical soliton formation. We show that a pulsed probe field and a pulsed FWM …
