Randomized trial reports dynamical switching between EIT and EIA in a Λ-type system, suggesting novel applications for optical devices.

This research aims to demonstrate a method for switching between transparency and absorption using a Λ-type atomic system.
Utilized two lasers to achieve dynamical switching between EIT and EIA.
Applied a weak magnetic field to resolve transitions into Zeeman-split subsystems.
Employed theoretical analysis based on dressed-state perturbation theory.
Identified an effective N-type pathway as the origin of switching.
Demonstrated that the EIT-EIA transition arises from quantum interference between secondary dressed states.
Generated tunable dual transparency windows, allowing for advanced signal routing applications.

Liu et al. (2026) studied this question.
