Paper Abstract

A novel scheme of optical packet power equalization is proposed by utilizing the gain characteristic of FP-SOA sensitive to input optical power. The steep gain descending curve with the carrier density provides that the high-power input optical signal obtains the low gain and the low-power one achieves the high gain. Real-time controlling mechanism according to input optical power is aborted in this scheme. The working principle of optical power equalizer based on FP-SOA is introduced in detail. The simulations show that 10 dB pulse peak power variation can be clamped in less than 1 dB. The impact of the injecting current, pulse width and pulse period are investigated and discussed.
