我们展示了一种新型光谱仪，采用光子晶体图案来耦合来自透明衬底的波导光。该光谱仪由光子晶体图案阵列组成，在玻璃基板上的聚合物中纳米制造，与相机相结合。照相机捕获从图案化衬底耦合出的光的图像;图案阵列产生不同波长带的强度的空间分辨图。使用光子晶体图案响应函数将图像的强度图转换成光谱。我们提出了一个概念证明，表征白色LED与我们的光子晶体光谱仪。(C)2010年美国光学学会
We demonstrate a new kind of optical spectrometer employing photonic crystal patterns to outcouple waveguided light from a transparent substrate. This spectrometer consists of an array of photonic crystal patterns, nanofabricated in a polymer on a glass substrate, combined with a camera. The camera captures an image of the light outcoupled from the patterned substrate; the array of patterns produces a spatially resolved map of intensities for different wavelength bands. The intensity map of the image is converted into a spectrum using the photonic crystal pattern response functions. We present a proof of concept by characterizing a white LED with our photonic crystal spectrometer. (C) 2010 Optical Society of America
