我们成功地制作了通道波导利用光子晶体（PhC）的色散具有非常低的损耗/splsim/0.1dB/mm的自克隆方法。通过改进工艺条件和调整纤芯宽度，达到了降低损耗的目的。传播损耗的结果可以被视为一个“里程碑”，它使我们能够实现实际的相位编码电路，包含功能组件，如色散均衡器和高Q波长滤波器。
We successfully fabricated channel waveguides utilizing photonic crystal (PhC) dispersion having a very low loss of /spl sim/0.1 dB/mm by the autocloning method. We achieved the loss reduction by improving the fabrication condition and adjusting the core width. The result of propagation loss can be regarded as a "milestone," and it enables us to realize practical PhC circuits that contain functional components such as chromatic dispersion equalizers and high Q wavelength filters.
