Functional plasmonic nanocircuits with low insertion and propagation losses.
We experimentally demonstrate plasmonic nanocircuits operating as subdiffraction directional couplers optically excited with high efficiency from free-space using optical Yagi-Uda style antennas at λ0 = 1550 nm. The optical Yagi-Uda style antennas are designed to feed channel plasmon waveguides with high efficiency (45% in coupling, 60% total emission), narrow angular directivity (<40°), and lo...

∗To whom correspondence should be addressed †University of Erlangen ‡Caltech uum light source is spectrally filtered by a programmed acousto-optic tunable filter (operated at λ = 1200− 1850nm) (NKT Koheras, SuperK Extreme) and is subsequently directed through a polarization filter (1) and a non-polarizing beam splitter (NPBS), that directs 50% of the power to a reference diode (InGaAs). The mai...
متن کاملHybrid superprism with low insertion losses and suppressed cross-talk.
We demonstrate with the two-dimensional finite-difference time-domain method that an adiabatic transition in a superprism with an interface along the [1 2 ] direction enhances the transmission through the superprism to more than 90% (-0.5 dB) over the wavelength range 1.47-1.68 mum , including the telecommunication C and L bands. We also show that diffraction governed by a quasinegative index o...
متن کاملElements for plasmonic nanocircuits with three-dimensional slot waveguides.
Over the last decade, the fi eld of plasmonics has received sig-nifi cant attention for its ability to utilize engineered metallic nanostructures to manipulate the fl ow of light down to the deep subwavelength scale (see, for example, recent reviews [ 1–4 ]). Extended metal structures can serve as compact optical waveguides that can transport information in the form of surface plasmon-polariton...
متن کاملCMOS-Compatible Plasmonic Nanocircuits for On-Chip Integration
Silicon photonics is merging as a unified platform for driving photonic based telecommunications and for local photonic based interconnect but it suffers from large footprint as compared with the nanoelectronics. Plasmonics is an attractive alternative for nanophotonics. In this work, two CMOS compatible plasmonic waveguide platforms are compared. One is the horizontal metalinsulator-Si-insulat...
