研究目的

Investigating the non-reciprocal optical transmission in hot rubidium atoms due to the interplay between thermal motion and electromagnetically induced transparency.

研究成果

The research demonstrates that high-temperature EIT can be advantageous for breaking reciprocity, with the desired non-reciprocal response disappearing when atoms are cooled down to cryogenic temperatures. This challenges the widely held view that lower temperatures result in better responses. Future works should address the potential for miniaturized, integrated systems and the maximum power up to which this approach can work.

研究不足

The amount of non-reciprocity that can be attained after a single pass through the material is expected to be limited. The approach may pose an upper limit for the probe power, possibly preventing high-power applications. The energy level broadening related to the microscopic Doppler effect may pose limitations in the case of very weak probe signals.
