Silicon photonics - Wikipedia Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems. The silicon typically lies on top of a layer of silica in what ... Horizontal Slot Waveguides for Silicon Photonics Back-End... 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
Potential of slot waveguides for silicon-based optical interconnects Yehea Ismail, Hosam Mekawey, Rania Gamal and Mohamed A. Swillam Compact dielectric and plasmonic slot waveguides have low loss characteristics and can be fabricated in a CMOS-compatible manner, and are thus suitable for integration in modern integrated circuits. Silicon-on-Insulator Slot Waveguides: Theory and In fact, slot waveguides have become the key element in order to implement organic materials into silicon photonics. Beside the strip and slot waveguide, the strip-loaded slot waveguide is utilized in this work. The cross section of each waveguide type is shown in Figure 1.
