我们展示了一个光学头处理系统，使用1.55 μm偏振垂直腔面发射激光器（VCSEL），作为一个全光与门和保持元件。取决于4位报头中的1位的状态，VCSEL保持两个正交偏振状态之一。VCSEL输出的光通过偏振器切换并保持光开关的输出状态。这使得有效载荷能够被发送到由报头确定的目的地。偏振VCSEL的特性实现了低功耗和低延迟操作。该系统还具有处理超快光分组中涉及的多比特光报头的潜力。
We demonstrate an optical header processing system using a 1.55-μm polarization bistable vertical-cavity surface-emitting laser (VCSEL) that operates as an all-optical AND gate and a holding element. Depending on the state of 1 bit in the 4-bit header, the VCSEL held one of two-orthogonal polarization states. The light of the VCSEL output through a polarizer switched and held the output state of an optical switch. This enables the payload to be sent to the destination determined by the header. The characteristics of the polarization bistable VCSEL enable low-power consumption and lower latency operation. The system also has the potential to process multibit optical headers involved in ultrafast optical packets.
