摘要

提出了一种基于二维光子晶体的3位码转换器，利用六边形晶格将二进制码转换为灰度码。在双t型波导中采用六角形硅柱，通过异或门实现码流变换器。采用异或逻辑门的级联布局，利用干扰效应实现输出。采用时域有限差分方法对所设计的码转换器进行了性能分析和设计。通过优化折射率和硅棒半径值，实现了对比度为12.557 dB的二灰码转换器。

Photonic Crystal Based Code Converter-Binary to Gray Code

We proposed a two dimensional photonic crystal based 3-bit code converter which converts binary codes to gray codes using hexagonal lattice. Using hexagonal silicon pillars in dual T-shaped waveguides code converter is realized by means of XOR gates. By employing the cascaded layout of XOR logic gates, the output can be arrived by using interference effect. Finite Difference Time Domain methodology is used to design and analyze the performance of the designed code converters. The design renders a contrast ratio of 12.557 dB for the binary to gray code converter with optimized refractive index and silicon rod radius values.
