Light has many uses, one of its biggest applications is in optical communications systems where a laser is switched on and off to transmit data. There are also many applications in the world of medicine, biology and biochemistry and tradiationally these have required very expensive, very large pieces of equipment. Currently the life sciences are required to look at smaller and smaller samples, sometimes down to the size of a single molecule. What this means is that the world of nanotechnology could be be used to create very small scale pieces of equipment that shine light onto very small samples and observe the light emitted by the samples. This then enables scientists to understand many important properties of the material. To work with light at these very small scales is very difficult, but recently, a new technology known as Photonic crystals(PhCs) has made breakthroughs in the way light can be confined and controlled. To make Photonic crystals nanofabrication procedures are need that are coming into mainstream use and they are now being applied in many different disciplines. This project will look to use PhCs to guide light onto a sample and then guide light emitted by the sample at a different wavelength towards a detector. A very small light source, a laser, will be included on the chip to make a very compact measurement device. The beauty of this approach is that 1000's of these devices could be placed on to a chip to measure many different samples simultaneously. This is the approach that is need for decoding genes to enable new drugs to be made.

光有很多用途，它最大的应用之一是在光通信系统中，激光被打开和关闭来传输数据。在医学、生物学和生物化学领域也有许多应用，传统上这些应用都需要非常昂贵、非常大的设备。目前，生命科学需要研究越来越小的样本，有时甚至小到单个分子的大小。这意味着纳米技术的世界可以用来制造非常小的设备，这些设备可以将光照射到非常小的样品上，并观察样品发出的光。这使科学家能够了解材料的许多重要特性。在如此小的尺度上处理光是非常困难的，但最近，一种被称为光子晶体（PhCs）的新技术在限制和控制光的方式上取得了突破。为了制造光子晶体，纳米工艺已经成为主流应用，并在许多不同的学科中得到应用。该项目将使用PhCs将光引导到样品上，然后将样品发出的不同波长的光引导到探测器上。一个非常小的光源，一个激光，将包括在芯片上，使一个非常紧凑的测量设备。这种方法的美妙之处在于，1000个这样的设备可以放在一个芯片上，同时测量许多不同的样品。这是解码基因以制造新药所需要的方法。
