Abstract
We propose a microwave signal generation device using difference frequency
generation in a periodically-poled LiTaO$_{3}$ rectangular waveguide. In the experiment, a microwave signal was
successfully generated at the designed frequency of 15 GHz from the
intensity modulated optical signal. The measured frequency response of the
fabricated proto-type device was in good agreement with the theoretically
expected ones. We expect the proposed device can be useful for
high-frequency signal generation, detections of the vector modulation
optical signal, and the optical clock signal.
