This paper investigates the impact of the radial ionization profile of proton on SEU sensitivity for nanoscale devices. Intrinsic radial track structures of energy deposition of protons (from 0.5 to 2 MeV) in a silicon box with of Si over-layer and a 100-nm silicon film were investigated. The orders of magnitude of the radial deposition is around 200 to 300 nm. Approaches based on punctual...
A multimode interference (MMI) polarization splitter with easy fabrication process was demonstrated in Silicon-On-Insulator substrate. The minimum device size, 8 µm×1034 µm was designed by Quasi-state imaging effect theory. Numerical simulations show that this optimized MMI polarization splitter has a good fabrication tolerance. The tolerance of width and length is ±0.04 µm and ± 10 µm for transverse...
We demonstrate here the fabrication of integrated tracking (horizontal) and focusing (vertical) micro lens actuators which are implemented on silicon-on-insulator (SOI) wafer using silicon bulk micromachining. The micro actuators that consist of flexures, a lens holder and comb structures with electrodes can realize two-dimensional movements of one objective lens for optical storage applications....
We demonstrate three-dimensional simulation of a third order silicon-based grating with full-width-half-maximum (FWHM) reflection bandwidth of 4nm. This provides more than 2 orders of magnitude improvement over a conventional side-walled grating structure. The relationship of grating performance over the infra-red wavelength range is also presented.
In this work, we demonstrate two- and three-dimensional (3D) simulations of an active silicon-based photonic crystal chromatic dispersion compensator utilizing the free carrier dispersion effect. The device has a low power consumption of 114nW and its intrinsic device modulation speed is predicted to function at 40.5MHz. Due to the device architecture, simulation must be carried out in 3D so as to...
