| Research Abstract |
Optical rectification diode(OR) devices based on metamolecules of gold nanoparticles were investigated. This novel device rectifies optical electric fields directly. We fabricated the OR devices with a number of metamolecules, and successfully observed the OR signal. With the parameters obtained in these experiments, we theoretically evaluated the OR signals from a single metamolecule using various electrode in different shapes, and found that the signal can be detected over the noise level, if we use a pair of cylindrical electrodes with an appropriate size.
