A key device in future high speed short reach interconnect technology will be the optical modulator. These devices, in silicon, have experienced dramatic improvements over the last 6 years and the modulation bandwidth has increased from a few tens of MHz to over 30 GHz. However, the demands of optical interconnects are significant. Here we describe an(More)
Direct tunneling gate currents of ultrathin gate oxide thickness metal oxide semiconductor field effect transistors ͑MOSFETs͒ are modeled in a two-step calculation procedure based on the treatment of physical microscopic data acquired during Monte Carlo device simulation. Gate currents are obtained by weighting the carrier perpendicular energy distribution(More)
In this paper, we report our recent results about slotted photonic structures for hybrid on-chip integration in silicon photonics. Explored schemes cover hollow core waveguide optimized micro-ring resonators, slot photonic crystal cavities, and slow light slotted waveguides, all aiming at the enhancement of light-matter interactions. A comparison between(More)
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. We experimentally demonstrate that such materials can be incorporated in 700(More)
Waveguide amplifiers have always been significant key components for optical communication. Unfortunately, the low concentration of rare earth ions doped in the host material and the inadequate optimization of the waveguide structure have been the common bottleneck limitations. Here, a novel material, NaYF4/NaLuF4: 20% Yb(3+), 2% Er(3+)(More)
In this paper, we report a series of slot photonic crystal heterostructure cavities with resonant wavelengths in the range of 1.3 μm - 1.6 μm. These cavities, which have a wide range operation as well as high Q/V factors (above 800,000), can be used for various applications based on the integration of active materials in the silicon photonics(More)
In this work, a deep understanding on performance compromises in the design of Silicon phase modulators is presented. Simplified modelling of Silicon modulators is presented and validated against full simulation. It is thus used to provide an analysis of compromises in the design of depletion and injection based modulators. Furthermore, experimental(More)
