2. Silicon nanophotonic components for an integrated refractometric sensor array.

Author

Muellner, P., Bruck, R., Hainberger, R., Karl, M., Baus, M., and Wahlbrink, T.

Abstract

Abstract: We present a novel wavelength multiplexing concept for an integrated sensor array based on SOI photonic MachZehnder interferometers. The characteristics of the entire device are discussed and the design, performed on the basis of FEM and 3D FDTD simulations, as well as first measurements of the nanophotonic key components–micro ring resonators and a photonic wire Bragg gratings–are presented.

Abstract

Abstract: Reactive ion etch (RIE) processes with HBr/O2 chemistry are optimized for processing of functional nanostructures based on silicon and polysilicon. The etch rate, etch selectivity, anisotropy and sidewall roughness are investigated for specific applications. The potential of this process technology for nanoscale functional devices is demonstrated by MOSFETs with 12nm gate length and optimized photonic devices with ultrahigh Q-factors.

Abstract

Silicon photonics offers tremendous potential for inexpensive high-yield photonic-electronic integration. Besides conventional dielectric waveguides, plasmonic structures can also be efficiently realized on the silicon photonic platform, reducing device footprint by more than an order of magnitude. However, neither silicon nor metals exhibit appreciable second-order opti-cal nonlinearities, thereby making efficient electro-optic modula-tors challenging to realize. These deficiencies can be overcome by the concepts of silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH) integration, which combine silicon-on-insulator (SOI) waveguides and plasmonic nanostructures with organic electro-optic cladding materials.

Abstract

Limitations of silicon photonics can be overcome by hybrid integration of silicon photonic or plasmonic circuits with organic materials or by photonic multi-chip systems. We give an overview on our recent progress regarding both silicon-organic hybrid (SOH) integration and multi-chip integration enabled by photonic wire bonding.
