Supressing optical loss in nanostructured metals by increasing self-inductance and electron path length

摘要

An optoelectronic device configured to operate at an electromagnetic radiation frequency having metal wire electrodes that are optically transparent as a result of the wires having an effective plasma frequency that is equal to or lower than the electromagnetic frequency at which the device operates. The effective plasma frequency of the wire is lowered by configuring the path of the wire between the terminal ends to be meandering, serpentine, U-shaped and in other non-linear configurations.
