摘　　要：提出了一种在波长双环路光电振荡器(OEO)中,利用啁啾压缩和孤子压缩效应产生光窄脉冲的有效方案。此方案能够同时产生双波长光窄脉冲。将双环路OEO产生的高质量微波信号调制到系统中的直调激光器和相位调制器上,产生光脉冲和光啁啾。调节直调激光器和相位调制器之间的延时量,从而获得最大的啁啾率。利用色散补偿光纤和高非线性光纤对光脉冲进行啁啾压缩和光孤子压缩,使得光脉冲最终压窄至1.2ps。采用锁相环技术对系统腔长进行有效控制,使光脉冲的长期稳定性得到改善。One effective scheme to generate optical short pulses based on chirp compression and soliton compression effects in the dual-loop optoelectronic oscillator （OEO） with different wavelengths is proposed. Dual-wavelength optical short pulses can be generated simultaneously with the proposed scheme. By modulating the high-quality microwave signal generated by the dual-loop OEO into the directly modulated lasers and the phase modulator, optical pulses and chirps can be obtained. The maximum chirp rate of the optical pulses is achieved by adjusting the optical delay between the directly modulated laser and the phase modulator. The chirp compression and soliton compression of optical pulses are conducted by utilizing the dispersion compensation fiber and the highly nonlinear fiber, respectively and the final optical pulse width is as narrow as 1.2 ps. After the system cavity length is effectively controlled with the phase-locked-loop technology, the long-term stability of optical pulses is further improved.
