Nanocrystals route Silicon Optics

项目摘要

Silicon chips have revolutionised the way we live our lives. Silicon is used in almost all electronic circuitry. However, there is one area of electronics that, at the moment, silicon cannnot be used to fill; that is in the emission of light. Silicon cannot normally emit light, but nearly all telecommunications and internet data transfer is currently done using light transmitted down fibre optics. So in everyones home signals are encoded by silicon and transmitted down wires to a station where other (expensive) components combine these signals and send light down fibres. If cheap silicon light emitters were available, the fibre optics could be brought into everyones homes and the data rate into and out of our homes would increase enormously. The applicants intend to collaborate with international research groups who are trying to make silicon emit light using tiny clumps of silicon called nanocrystals . These nanocrystals can emit light in the visible and can be made to emit in the infrared by adding erbium atoms to them. A number of techniques available in Manchester, Guildford and Japan will be applied to silicon chips made in Canada to understand the light emission and to try to make silicon chips that emit light. In addition we will work with the UK company Qinetiq to investigate other uses of the nanocrystals in sending coded messages down fibers.

硅芯片彻底改变了我们的生活方式。硅几乎用于所有的电子电路。然而，有一个领域的电子产品，目前，硅不能用来填补，这是在发光。硅通常不能发光，但目前几乎所有的电信和互联网数据传输都是通过光纤传输的光来完成的。因此，每个人家里的信号都是由硅编码的，然后通过电线传输到一个站，在那里，其他（昂贵的）组件联合收割机将这些信号组合起来，然后通过光纤发送光。如果有便宜的硅光发射器，光纤就可以进入每个人的家庭，进出我们家庭的数据速率将大大增加。申请人打算与国际研究小组合作，这些研究小组试图利用称为纳米晶体的微小硅块使硅发光。这些纳米晶体可以发射可见光，并且可以通过向其中添加铒原子来使其发射红外线。曼彻斯特、吉尔福德和日本的一些技术将应用于加拿大制造的硅芯片，以了解光的发射，并试图制造发光的硅芯片。此外，我们将与英国Qinetiq公司合作，研究纳米晶体在光纤中发送编码信息的其他用途。
