The work demonstrates an alternative solution to costly silicon-on-insulator photonics. The proposed solution uses bulk silicon wafers and thin film deposited waveguides. Back-end deposited horizontal slot grating couplers and waveguides are realized by multi-layers of amorphous silicon and high-k materials. OSA | Nanofocusing in SOI-based hybrid plasmonic metal slot ... Through a process of efficient dielectric to metallic waveguide mode conversion, we calculate a >400-fold field intensity enhancement in a silicon photonics compatible nanofocusing device. A metallic slot waveguide sits on top of the silicon slab waveguide with nanofocusing being achieved by tapering the slot width gradually. We evaluate the conversion between the numerous photonic modes of ... OSA | Nonlinearity of optimized silicon photonic slot waveguides In this numerical study, we show that by exploiting the advantages of the horizontal silicon slot waveguide structure the nonlinear interaction can be significantly increased compared to vertical slot waveguides. The deposition of a 20 nm thin optically nonlinear layer with low refractive index sandwiched between two silicon wires of 220 nm width and 205 nm height could enable a nonlinearity ...

The silicon is usually patterned with sub-micrometre precision, into microphotonic components. Ultra-high on-chip optical gain in erbium-based hybrid slot ... Waveguide fabrication. In this work, we fabricated and studied Er:Al 2 O 3 –Si 3 N 4 hybrid slot waveguides. Silicon nitride (Si 3 N 4) was chosen as the passive waveguide material due to its ... Home - Helios project The mission of the large scale integrating project HELIOS was to make CMOS photonics accessible to a broad circle of users. During 4 years, from 2008 to 2012, the HELIOS consortium developed innovative means to combine a photonic layer with a CMOS circuit, using microelectronics fabrication processes.

INTRODUCTION Coupling plasmonic and silicon photonics is the best way to Low-index slot serves as waveguide | Laser Focus World Because the slot waveguide does not rely on resonance principles, it is largely insensitive to wavelength. The researchers made waveguides, directional couplers, and resonator devices with the slot geometry, using silicon-on-insulator substrates fabricated with reactive ion etching and electron-beam lithography. Experimental GVD engineering in slow light slot photonic ... The use in silicon photonics of the new optical materials developed in soft matter science (e.g. polymers, liquids) is delicate because their low refractive index weakens the confinement of light and prevents an efficient control of the dispersion properties through the geometry. ...
