Abstract

Optoelectronics links in future radar systems require the generation and control of time delays for large frequency bandwidth (typically 20 GHz) microwave signals to be transmitted or/and processed. Compact structures wherein slow waves propagate have a role to play in a such context applying the so group delay generated onto the microwave signals. We present here an original architecture to slow down the light in semi-conductor amplifier (SOA), based on a dual frequency optical beam interfering inside the gain medium of the SOA as wave mixing due to population oscillation [1]
