Lossless intensity-dependent dispersion in coherently prepared multi-state atom using EIT

摘要

This work studies the lossless intensity-dependent dispersion in coherently prepared multi-state atoms using electromagnetically induced transparency (EIT). This study also describes the chain /spl Lambda/ atoms, identifies realistic conditions for observing chain /spl Lambda/ atoms, presents extended results where propagation effects are taken into account and explores the prospects for using such atoms in novel quantum devices.
