论文摘要
原子蒸气为在广泛的电磁频谱上操纵电磁信号提供了许多机会。在这里,具有音频调制的微波信号通过利用原子微波到光学双共振来编码光学信号中的信息,并通过谐振高Q微波腔扩大的磁场耦合。使用这种方法,将音频信号编码为GHz载波中的振幅或频率调制,通过电缆或自由空间传输,通过腔体增强的Atom-Microwave相互作用进行解调,最后是光学检测到的,以提取原始信息。这种原子腔信号转导技术提供了一种强大的手段,可以通过微波和光场之间传输信息,所有这些都使用没有主动电子的相对简单的实验设置。
Atomic vapors offer many opportunities for manipulating electromagnetic signals across a broad range of the electromagnetic spectrum. Here, a microwave signal with an audio-frequency modulation encodes information in an optical signal by exploiting an atomic microwave-to-optical double resonance, and magnetic-field coupling that is amplified by a resonant high-Q microwave cavity. Using this approach, audio signals are encoded as amplitude or frequency modulations in a GHz carrier, transmitted through a cable or over free space, demodulated through cavity-enhanced atom-microwave interactions, and finally, optically detected to extract the original information. This atom-cavity signal transduction technique provides a powerful means by which to transfer information between microwave and optical fields, all using a relatively simple experimental setup without active electronics.
