One of the most serious challenges facing exponential performance growth in the information industry is the bandwidth bottleneck in interchip interconnects. We propose a photonics–electronics convergence system in response to this issue. To demonstrate the feasibility of the system, we fabricated a silicon optical interposer integrated with arrayed laser diodes, spot-size converters, optical splitters, optical modulators, photodetectors, and optical waveguides on a single silicon substrate. Using this system, 20 Gbps error-free data links and a 30 Tbps/cm2 bandwidth density were achieved. This bandwidth density is sufficient to meet the interchip interconnect requirements for the late 2010s.

检测具有特殊空间结构的IC板引脚焊点缺陷时,相机镜头相对于引脚平面会有一定的倾斜角度,在特定的范围内获取图像清晰,超过此范围图像出现离焦模糊。针对此问题进行了研究,建立了景深的数学模型,推导出合理拍摄角度的公式,并通过实验进行了分析和验证。
对于红外输出图像的非均匀性,通常可采用两点校正法和神经网络法进行改善。但两点校正法不能有效地克服环境温度漂移的影响;神经网络法收敛缓慢,使静止图像逐渐融入背景,导致运动目标出现伪像。提出一种多本底采样自适应非均匀校正算法,在不同的环境温度点采集多组高低温本底,根据最小二乘法拟合计算得到非均匀校正系数和环境温度的关系,根据环境温度的改变自适应完成非均匀校正。测试结果表明,该方法简单可行,能够较好地克
