Rare earth ions embedded in crystals are natural high-quality-factor resonators that can be used for processing optically-carried broadband radio-frequency signals. This chapter focuses on the radio-frequency spectrum analysis function and describes different architectures that are designed to reach tens of gigahertz instantaneous bandwidth with submegahertz resolution. Various approaches are considered. The active material may act as a spectral buffer memory. Instead one may store a processing… CONTINUE READING
