| 摘 要： | 光标记技术是一种实现光分组交换的重要技术.文章提出并用实验验证了一种基于正交调制PolSK/Inverse-RZ的新型光标记方案,该方案用Inverse-RZ作载荷信号,用PolSK作标记信号.由于Inverse-RZ信号在比特"1"和比特"0"时都具有光功率,在PolSK信号检测时信息一直保持着,因此通常使用ASK信号标记的技术在消光比方面的限制被解决了.

| Abstract: | Optical label technology is an important technology to realize optical packet switch.We propose and experimentally demonstrate a novel orthogonal labeling scheme in optical packet switching by using Pol-SK/Inverse-RZ formats,this scheme use Inverse-RZ as the payload signal,and use PolSK as the label signal.Since the Inverse-RZ signal has optical power in both bit 1 and bit 0,the information is maintained for PolSK detection.Thus,the limitation of extinction radio(ER) of the ASK signal is eliminated. |
