In this paper, an all-optical miniaturized binary to gray code converter is designed and analyzed. The all-optical domain is now an alternative for electronic devices, where performance and speed are the key issues. Code converters are significantly used in digital data transmission in the areas of error detection and correction. Gray code is one of the cyclic codes, where the cyclic shift of each codeword is also a code word. An all-optical XOR gate, realized using a Y-shaped power combiner is used in this design to generate the desired gray code from the given binary code. The insertion loss and extinction ratio parameters are found to be 0.347 dB and 22.26 dB, respectively. The entire simulation is carried out using finite-difference time-domain method. The obtained practical results are verified mathematically using MATLAB.

本文设计并分析了一种全光小型化二进制格雷码转换器。全光域现在是电子设备的替代方案，其中性能和速度是关键问题。代码转换器在错误检测和纠正领域的数字数据传输中得到了广泛应用。格雷码是循环码之一，每个码字的循环移位也是一个码字。在该设计中使用了一个使用 Y 形功率组合器实现的全光 XOR 门，以从给定的二进制码生成所需的格雷码。插入损耗和消光比参数分别为 0.347 dB 和 22.26 dB。整个模拟是使用有限差分时域方法进行的。使用 MATLAB 对所获得的实际结果进行了数学验证。
