The high refractive index of silicon waveguides provide two benefits for sensing: 1. Rings can be made very small without reducing Q by bending loss, 2. The evanescent electric field at the silicon surface is very high, yielding high sensitivity for surface sensing. GVD control of low loss slot photonic crystal waveguides ...

slot waveguides exhibiting unexpectedly low propagation losses and a broadband sub-50 nm optical confinement. Keywords: surface plasmon polariton, metallic slot waveguides, co-directional couplers, silicon photonics, plasmonics, integrated optics. I. 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. ... Low-loss silicon slot waveguides and couplers fabricated with ...

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 ... High Performance Optical Modulator Based on Electro-optic ... Interferometer (MZI), with slot photonic crystal waveguides (PCWs) incorporated in both the arms, as shown in Fig. 1 (a). We start with a silicon-on-insulator (SOI) substrate with 250nm-thick top silicon and 3µm-thick buried oxide (BOX) layers. The slot and holes of the PCWs are filled with an EO IEEE PHOTONICS TECHNOLOGY LETTERS, VOL. 28, NO. 1, JANUARY ...
