ABSTRACT:
Electrical signals with frequencies ranging from several tens of megahertz to hundreds of gigahertz are generated by detecting the optical output from a novel double-external-cavity diode laser system. The system provides a convenient means of measuring the frequency response of high speed photodetectors, and it can also be used for the optical generation and transmission of microwave or millimeter wave carriers in applications such as phased array radars.
