Integrated plasmon and dielectric waveguides

Abstract

Abstract:We have designed, fabricated and characterized surface plasmon waveguides for near infrared light in the telecommunications spectrum. These waveguides exhibit losses of -1.2dB/µm and can guide light around 0.5 µm bends. Light can also be efficiently coupled between more conventional silicon waveguides and these plasmon waveguides with compact couplers, and we demonstrate that surface plasmon optical devices can be constructed by using planar circuit fabrication techniques. The large optical field enhancements of metallic surface plasmon devices are expected to lead to a new class of plasmonic optical devices, which will take advantage of the large field enhancements at the surfaces of the plasmon waveguides for nonlinear or sensing functionality, while utilizing the low losses available in silicon waveguides to move light longer distances on chip.

Organic solid‐state integrated amplifiers and lasers

“…One of the attractive features of organic materials is their suitability for hybrid integration, that is, the concept of building photonic circuits by assembling different materials that excel in providing the functionalities of interest on a single chip [36,37]. Organic solid-state materials can be integrated onto a wide range of platforms without any limitations imposed by the requirement for lattice-matching associated with crystalline materials.…”

Surface plasmon interferometer in silicon-on-insulator: novel concept for an integrated biosensor

“…So the gold layer possesses two distinct surface-plasmon modes which propagate through the structure without influencing each-other. Exciting these modes is done by end-fire coupling from a regular SOI waveguide with the transverse-magnetic ground mode [10,11]. So one can see that this device is in fact an interferometer.…”

Numerical Study of Dielectric Resonant Gratings

“…In particular, the ability of plasmon nanostructures to manipulate with local density of the electromagnetic states has already been used in optical communication and biomedicine [2]. The ability of plasmon waveguides to conduct the light signal in the extents less than diffraction limit will allow one to significantly reduce the sizes and increase the efficiency of integrated circuits used in radioelectronics [3,4]. In future, plasmon nanostructures will become a useful feature to explore the new physical phenomena in atom physics and quantum optics.…”
