德国和瑞士科学家联合研发用于芯片间数据传输的微型光电信号转换器
德国和瑞士科学家 芯片间数据传输 微型光电信号转换器
2015/11/17
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...

Since the first laser was invented in 1960, they’ve almost always given off heat — either as a useful tool, a byproduct or a fictional way to vanquish intergalactic enemies.But those concentrated beam...
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...
美国威斯康星大学研究人员创制柔性光电晶体管

美国威斯康星大学麦迪逊分校两位研究人员创制了一种柔性光电晶体管，可望改善众多光电器件的性能。
作为这所高等学府电气和计算机工程系纳米器件实验室一个研究小组的主管，教授马振强与一名同事联手，采用一种名为“翻转转移”的创新制造工艺，即把制作完成的光电晶体管翻转到一片塑料基底上。
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...

3D打印人造血管获重大突破
3D打印 人造血管
2015/9/9
德国弗朗霍夫激光技术研究所研究人员成功利用3D打印技术制造出人造血管，这一技术突破有望广泛应用在治愈皮肤创伤、人工皮肤再造和人造器官等医学领域。
重大事故受伤、大面积烧伤或肿瘤切除的病人经常需要对创面皮肤进行再造，目前的医疗技术只能对皮肤表层厚度（真皮和表皮）不超过200微米进行人工再造，而对包括皮下组织的几毫米厚完整皮肤系统还不能进行再造，因为涉及到血管组织，没有血管的养分供应，超过200微米...
