摘要

提出了一种基于逻辑异或门的光学生存时间(TTL)方法。采用两个基于soa的Mach-Zehnder干涉仪的级联，显示了封装等离子体TTL场的全光递减。通过仿真验证了工作原理，在1位减法器的输出处显示出良好的消光比(高于10 dB)。

All-optical decrementing of a packet’s time-to-live (TTL) field using logic XOR gates

A novel optical time-to-live (TTL) method based on the use of logic XOR gates is proposed. All-optical decrementing of a packetpsilas TTL field is shown employing a cascade of two SOA-based Mach-Zehnder interferometers. The principle of operation is validated by means of simulations, showing a good extinction ratio (higher than 10 dB) at the output of the 1-bit subtractor.
