【摘要】 从微腔半导体激光器考虑相位变化的速率方程和光纤非线性薛定谔方程出发,数值模拟了交变电流注入下微腔半导体激光器内腔和光纤外腔中的光振荡过程,研究了光孤子形成的可能性。结果表明,合理选择自发发射因子、有源区体积、相位振幅耦合参数、附加相位参量等内外腔参数,可以实现稳定的孤子脉冲输出。1更多还原

【Abstract】 Basing on the rate equations of microcavity semiconductor lasers and the nonlinear Schro&&dinger equation in optical fibres,the optical oscillating process in the interal and exteral cavity is numerically simulated,the possibility of soliton formation is discussed. The results show that the spontaneous emission factor,the volume of the active region and phase-amplitude coupling coefficient affect the stabilizing progress of output soliton pulses and distortion can take place if they aren抰 choosed properly.更多还原
