利用芯片速率为640 Gchips/s的超结构光纤布拉格光栅（SSFBG），实验证明了记录长度为511片的光码的生成和识别。具有很高的反射率（92%）和高质量的相关特性。温度偏差公差约为+/- 0.3℃，在封装的温度稳定范围内（+/- 0.1℃）。实验结果与理论吻合较好。他们指出，SSFBG具有以超高芯片速率处理长光码的潜力，这可以显著提高系统的性能。
The generation and recognition of a record-length 511-chip optical code is experimentally demonstrated by use of a superstructured fiber Bragg grating (SSFBG) with a chip rate of 640 Gchips/s. Very high reflectivity (92%) is achieved with high-quality correlation properties. The temperature deviation tolerance is approximately +/- 0.3 degrees C, which is within the package's temperature stability range (+/- 0.1 degrees C). Experimental results show good agreement with the theory. They indicate the SSFBG's potential for processing a long optical code with an ultrahigh chip rate, which could significantly improve the system's performance.
