2.高温混合硅微型环激光热分流术
[计算机、通信和其他电子设备制造业] [2015-10-01]
A hybrid silicon micro-ring laser is a good candidate as light source for low cost and low power consumption data links [1]. However, thermal issues are one of major obstacles to achieve higher energy efficiency and higher integration density. The thick buried oxide (BOX) layer in silicon on insulator (SOI) has a poor thermal conductivity and blocks the heat dissipating into the heat sink. Furthermore ring lasers have a higher thermal impedance due to their small footprint, which makes the performance degrade rapidly at high temperatures [2]. In previous work we reduced device heating with a metal thermal shunt design [3]. In this paper we investigate better thermal management of hybrid silicon ring lasers with an optimized thermal shunt structure.

6.使用偏振照明和单片彩色摄像机的二分结果
[计算机、通信和其他电子设备制造业] [2015-09-09]
The report is not the result of a focused study but an accumulation of issues encountered during a variety of projects requiring the use of polarized light, addressing color-consistency problems experienced using commercial, single-sensor digital cameras with linearly polarized illuminants. Using an unfixed polarizing film sheet contrasts to using a commercial polarimeter. Experiences with on-camera processing, white balance, color space, file format, tethered operation, and the use of PC processing software are discussed.

7.Xilinx覆晶芯片专家包的物理失效分析:LP2填充不足和ATI盖胶材料的任务环境对性质的影响
[计算机、通信和其他电子设备制造业] [2015-09-09]
The Xilinx Virtex 4QV and 5QV (V4 and V5) are next-generation field-programmable gate arrays (FPGAs) for space applications. However, there have been concerns within the space community regarding the non-hermeticity of V4/V5 packages; polymeric materials such as the underfill and lid adhesive will be directly exposed to the space environment. In this study, reliability concerns associated with the non-hermeticity of V4/V5 packages were investigated by studying properties and behavior of the underfill and the lid adhesvie materials used in V4/V5 packages.

8.监控介质激光加速器上解决梁的位置的设计
[计算机、通信和其他电子设备制造业] [2015-09-09]
We present a new concept for a beam position monitor with the unique ability to map particle beam position to a measurable wavelength. Coupled with an optical spectrograph, this beam position monitor is capable of sub-nanometer resolution. We describe one possible design, and through finite element frequency domain simulations, we show a resolution of 0.7 nanometers. Due to its high precision and ultra-compact form factor, this device is ideal for future x-ray sources and laser-driven particle accelerators 'on-a-chip'.

9.压缩质子束书写系统III的离子源发展
[计算机、通信和其他电子设备制造业] [2015-09-09]
Through a technical exchange with Delft University, the NUS research team has gained valuable knowledge and have achieved the first results with the electron-impact ion source system. Through this exchange, the team has achieved a realistic design for the ion source test bench which has produced its first beams at 3 keV and is currently being tested in Singapore. In a next stage, this system will be employed at ion energies of up to 200 keV. Electron beam calculations have been performed to evaluate different electron guns for their effectiveness in ionizing hydrogen gas molecules in our proposed configuration. Our calculations show that the proposed PBW system is expected to write as fast as commercial electron beam writing systems at sub 10nm, without proximity effects from nearby fabricated features. Several electron impact ionization chips have been designed and tested at Delft and Singapore. At the same time, the new proton beam writing beam line developed under previous grant efforts has been further improved and proton beams now can be focused to 13nm x 29nm.

[计算机、通信和其他电子设备制造业] [2015-09-09]
Next-generation processor architectures (multi-core, multi-threaded) hold the promise of delivering enormous amounts of compute power in a small form factor and with low power requirements. However, new programming models are required to realize this potential. Our objectives are to deploy data processing and vehicle control systems onto a variety of systems on a chip (SOC) to provide more autonomous functionality.
