1·They wanted to build a waveguide, a structure designed to send light in a particular direction, by drilling carefully spaced holes in a gallium arsenide crystal.
他们只是想通过在砷化镓晶体上钻一些有着细心安排间距的小孔来制造波导（一种能令光传播到特定方向的结构）。
2·Using nanofabrication techniques, the researchers etched tiny holes into the nitride to make a desired pattern, giving the waveguide the cloaking refractive index profile.
通过纳米制备技术研究者在氮化硅中刻蚀出许多空洞以构成所需图案，使得波导具有合适的隐形折射率。
3·To see if disorder could help materials trap light, Lodahl and colleagues built a new waveguide, this time deliberately placing the holes at random intervals.
为了弄清这种无序是否能有助于材料捕获光，Lodahl和同事研制了一种新型波导，这次他们特意在随机间隔上打上小孔。
4·They also embedded quantum dots, tiny semiconductors that can emit a single photon at a time, in the waveguide as a proxy for atoms that could become entangled with the photons.
他们还在波导中嵌入了量子点(一种能释放单光子的微小半导体)作为代理来使原子与光子产生纠缠。
5·Ocean Acoustic Waveguide Remote Sensing is an especially exciting advance.
海洋声学波导遥测是一种特别令人兴奋的先进技术。
