中文摘要 本篇論文研究基於電磁波引發透明機制的雙Λ型共振反向四波混頻系統,在光學密度為19的冷原子中,我們觀察到光波長從780奈米轉換到795奈米大約有66%的轉換效率。另外,我們也證實在雙Λ型的四波混頻系統中,可以利用雙光子調變補償相位不匹配。根據我們發展的理論模型,這種四波混頻系統在光學密度200及理想的條件下,可以達到96% 的轉換效率。這種波長轉換系統能夠實現接近100%的轉換效率,因此可以提供給全光學量子資訊處理,作為一種製備有效量子轉頻器的簡單方案。
英文摘要 In this thesis, we study a highly efficient resonant backward four-wave mixing (FWM) scheme based on double-Λ electromagnetically induced transparency (EIT) system. A wavelength conversion from 780 to 795 nm with approximately 66% conversion efficiency (CE) is observed by using this backward FWM scheme at an optical density (OD) of 19 in cold rubidium atoms. Furthermore, we demonstrate that the phase mismatching can be compensated by adjusting two-photon detuning in this double-Λ FWM scheme. According to our theoretical model, the present scheme can achieve 96% CE using a medium with a large OD of 200 under ideal conditions. Such wavelength conversion scheme can achieve a near-unity CE, thus providing an easy method of implementing an efficient quantum frequency converter for all-optical quantum information processing.
