A scheme for the direct conversion of millimeter and THz waves to optical signals is introduced. The compact device consists of a plasmonic phase modulator that is seamlessly cointegrated with an antenna. Neither high-speed electronics nor electronic amplification is required to drive the modulator. A built-in enhancement of the electric field by a factor(More)
The arrival of the Single-Atom Transistor (SAT) in 2004, a quantum device operated at room temperature, allowed for the first controlled switching of an electrical current by the reproducible relocation of one single metal atom [1]. At the same time this component established the feasibility of transistors completely made of metals. Meanwhile, many(More)
Speed, footprint, power consumption and economiy of costs are key factors in the field of communications. The new field of plasmonics promises THz bandwidth devices with a micrometer footprint operating with fJ/bit at prices that scale similar to what is known from the CMOS industry. In this paper we will review recent advances in the field of plasmonics.(More)
