Abstract
We have assembled and characterized a multimode optoelectronic oscillator with integrated optical filter for detecting low-power radio-frequency (RF) signals. The system can selectively amplify RF signals from 1 to 6 GHz. The input signals can be as low as - 83 dBm with a compression dynamic range of 72 dB. Using an integrated silicon optical filter facilitates channelization of the amplified RF signal from 1 to 3 GHz by reducing the gain for signals above 3 GHz. Future system improvements are discussed.
