Hybrid integration offers new opportunities for light management at nanoscale. We will in this paper review some of the practical aspects of metallic nanostructures integrated on dielectric waveguide including light scattering for integrated spectroscopy, sub-wavelength waveguiding and metamaterials for polarization conversion.
We address the potential of a metamaterials in a guided wave configuration for applications in the near IR domain. We consider a hybrid type structure made of 2D metamaterial array over a high index slab waveguide, as for instance silicon our case. The experimental and modeling results show that effective index and loss level in such hybrid waveguides can be carefully controlled by the engineering...
In this paper we address the potential of metallic metamaterials in guided wave configurations to explore the possibility of their use for transformation optics applications in the near-infrared domain (λ = 1.5 µm). The experimentally investigated hybrid metamaterial structure is made of 2D array of 200×50×50 nm gold cut wires located on the top of high index silicon on insulator (SOI) waveguide....
The electromagnetic excitation of metallic nanoparticles (MNP) has attracted a great interest in the past decade due to the ability of surface plasmons to surpass the diffraction limit of conventional optics [1]. Chains of coupled resonant MNP have been proposed to allow transfer of electromagnetic energy from particle to particle at nanometer scales [2]. However, the most of the work was focused...
The uniformity of a 300mm wafer has been analyzed through the study of resonant wavelength of ring resonators. SOI thickness variation can be compensated with the use of Ti-TiN heater.
We report on the fabrication, simulation and use of carbon nano-probes grown on the apex of polymer-tipped optical fibers. The carbon needles are used as near-field scattering probes to image light propagation in surface waveguides. The scattered light is selectively and efficiently coupled in the supporting optical fiber through the polymeric structure which is used here as a submicronic collection...
We numerically simulate chromatic and thermal dispersion in ring-resonator-based filters and validate the model with experimental data. A low-loss 1×8 multiplexer based on SCISSORs structure was designed with a bandwidth of 200GHz at −3dB and a crosstalk better than −13.5dB for each channel.
We developed a home-made Sample-Holder Unit used for 2D nano-positionning with millimeter traveling ranges. For each displacement axis, the system includes a long range traveling stage and a piezoelectric actuator for accurate positioning. Specific electronics is integrated according to metrological considerations, enhancing the repeatability performances. The aim of this work is to demonstrate that...
