We study phase-sensitive amplification of electromagnetically induced transparency in a warm ${}^{85}$Rb vapor wherein a microwave driving field couples the two lower-energy states of a {\Lambda} energy-level system thereby transforming into a {\Delta} system. Our theoretical description includes effects of ground-state coherence decay and temperature effects. In particular, we demonstrate that driving-field-enhanced electromagnetically induced transparency is robust against significant loss of…

Microwave assisted transparency in an M-system
In this work we theoretically study a five-level M-system whose two unpopulated ground states are coupled by a microwave (MW) field. The key feature which makes the M-system more efficient in…
Theoretical study of the control of absorption, transparency, and amplification in a microwave- and RF-driven four-level (Δ + ∇)-type closed-contour interaction system
This paper describes a theoretical study of the optical responses of an atomic medium to the probe field in a four-level (Δ + ∇)-type closed-contour interaction system driven by two pump laser fields…
Demonstration of a high-contrast optical switching in an atomic Delta system
We present an experimental study of a Δ system in a room temperature, dilute sample of 85Rb atoms. A Δ system in the D2 manifold of 85Rb is formed by connecting the two lower hyperfine energy levels…

TLDR
A hybrid, ground-state-coherence-assisted PSA of a near-infrared electromagnetic field using room-temperature 85Rb atoms possessing ground- state coherence is reported, the first such demonstration using atomic ensembles.
Phase and amplitude control of atomic grating in a three level closed lambda System
We have theoretically studied the electromagnetically induced grating (EIG) in a three-level closed Λ-type atomic system. The upper level is coupled to the two lower levels via a strong control and a…
