在本文中，我们将描述如何在基于波分复用（WDM）技术的光子分组交换系统中使用半导体激光二极管光放大器/门。首先，我们表明，当器件在波导材料的透明条件下使用时，即使输入信号功率超过 +18 dBm，也可以抑制交叉增益调制 (XGM)。然后我们讨论光信号的适当编码。实验结果表明，高比特率曼彻斯特编码使得能够在增益条件和透明条件下使用半导体激光二极管光放大器/门。最后，提出了一种利用半导体激光二极管光放大器作为分组功率均衡器的新型光子分组接收器。对于 10 Gb/s 曼彻斯特编码信号，该接收器可接受纳秒速度下 17 dB 的功率波动。
In this paper, we will describe how semiconductor laser diode optical amplifiers/gates can be used in the photonic packet switching systems based on wavelength division multiplexed (WDM) techniques. First, we show that cross-gain modulation (XGM) can be suppressed when the device is used in the transparent condition of the waveguide material even when the input signal power exceeds +18 dBm. We then discuss an appropriate encoding for the optical signal. Experimental results show that high bit rate Manchester-encoding enables the use of semiconductor laser diode optical amplifiers/gates in the gain condition as well as the transparent condition. Finally, a new photonic packet receiver which utilizes a semiconductor laser diode optical amplifier as a packet power equalizer is proposed. This receiver accepts 17 dB power fluctuation at nanosecond speed for 10 Gb/s Manchester-encoded signal.
