摘要

We propose an atomic filter configuration with large tunability based on selective optical-pumping-induced anisotropy. Theoretical simulation shows that the filter structure, by using a counterpropagating pump, can achieve higher transmission and a narrower passband than that using a copropagating pump due to the elimination of Doppler broadening. In addition, the filter's tunability over 100 GHz via Aulter-Townes splitting and filtering characteristics is analyzed.
