光处理信息 光电子芯片
2015/12/25
美国科学家称近日研发出世界上首个用光处理信息的光电子芯片。它依旧使用电子来计算，但是可以直接使用光来处理信息。这一成果或将打开超高速、低能耗数据处理的大门。研究结果2015年12月24日发表在《自然》期刊上。
While 3-D printers have become relatively cheap and available, 3-D scanners have lagged well behind. Now an algorithm developed by Brown University researchers may help bring high-quality 3-D scanning...

实现芯片间高速、低能耗数据传输关键单元是光电信号转换器，马赫 - 策德尔调制器（Mach-Zehnder-Modulator，MZM)是其中的关键技术之一。德国卡尔斯鲁厄技术研究院（KIT）和瑞士苏黎世联邦理工大学（ETH）的科研人员合作，研制出一种微型等离子体马赫-策德尔调制器，长度只有12.5微米，相当于头发丝直径的1/10，能将数字电信号以每秒108千兆（Gigabite）的速率转换成光信号...
Throughout optics and photonics, phase is normally controlled via an optical path difference. Although much less common, an alternative means for phase control exists: a geometric phase (GP) shift occ...
Imagine watching the World Cup or the Super Bowl in 3-D in the comfort of your own home. That option may be available sooner than you think. With support from the National Science Foundation (NSF), op...
In 2010, Michael Escuti received funding from the National Science Foundation (NSF) to study and make novel hologram technologies.He created a tool that did much more."Not long after we received the N...

最近，马普学会固态研究所的科学家们开发出了一种新光源，通过单分子把电脉冲转换成光脉冲，该分子就像一个光控晶体管的开关，这个开关甚至还能调节光的强度。由于分子打开和关闭的速度极快，这种光源能以千兆赫频率将电信号转换成光信号。虽然这样的分子光源产生的光很微弱，但已经可以用肉眼清晰分辨，因此将有望成为一种新的、有效的信息传输设备。
For many years, the focus of brain mapping was to examine changes in the brain that occur when people are attentively engaged in an activity. No one spent much time thinking about what happens to the ...
