Abstract

In this paper we propose and demonstrate a dynamic, narrow-bandpass frequency filter. This is generated in a rareearth ion-doped crystal using a combination of spectral hole burning and Stark shifting. This filter can toggle within one microsecond between absorption and transmission, with ∼60 dB difference in attenuation, in two separate 1 MHz wide spectral regions. The filter demonstrated here is specifically designed as a component in a rare-earth ion-based quantum repeater protocol. However, this is a general technique that could also be applied for amplitude or phase modulation, or switching between more complicated spectral profiles.
