Measurement of the Carrier Recovery Time in Semiconductor Optical Amplifier Based on Dual-Pump Four-Wave Mixing Technology 下载免费PDF全文
A scheme of measuring the carrier recovery time in semiconductor optical amplifiers (SOAs) based on dual pump Four-wave mixing technology is presented. The carrier recovery times under 120mA, 180mA 240mA and 300mA injected currents are measured to be 111ps, 81ps, 71ps and 53ps, respectively. The carrier recovery time of the spacing between the two umps is also investigated. The experimental results show that the conversion efficiency keeps constant when the spacing of the two pumps varies within a small range. 相似文献

Measurement of the carrier recovery time in SOA based on four-wave mixing on narrow-band ASE spectrum 下载免费PDF全文
Carrier recovery time is a key parameter that determines the performance of a semiconductor optical amplifier (SOA). A measurement method of carrier recovery time in SOA based on a nearly degenerate four-wave mixing of narrow-band amplified spontaneous emission (ASE) spectra is presented. The results show the carrier times are 50.2, 44.6, and 23.6 ps when the injected currents are 120, 180, and 240 mA, respectively, which are in agreement with the nominal values of the sample. 相似文献
