A semi-analytical dimensionless formula is presented for predicting the period-one frequency of an optically-injected laser over a wide range of injection powers and positive detunings. The result shows that for any given injected optical power, there exists an optimal detuning at which the period-one frequency is maximized. The formula is applied to a tabletop optical injection system with a commercially-available quantum-well distributed feedback laser with previously unknown design parameters. By extrapolating the linearity of the period-one frequencies at zero-detuning and weak-injection regimes, the physical control parameters of the laser are approximated to the analytical formula for wide ranges of injection powers and positive detunings. The accuracy of the model is experimentally verified, achieving period-one frequencies as high as 84.7 GHz.

强失谐可调光子振荡器

提出了一种半解析无量纲公式,用于在很宽的注入功率和正失谐范围内预测光学注入激光器的周期一频率。结果表明,对于任何给定的注入光功率,都存在一个最佳失谐,在该失谐处使第一周期频率最大化。该公式应用于桌面光学注入系统,该系统具有市售的量子阱分布反馈激光器,其设计参数以前未知。通过在零失谐和弱注入状态下外推第一周期频率的线性度,激光器的物理控制参数近似于大范围注入功率和正失谐的解析公式。通过实验验证了模型的准确性,实现了周期一频率高达84。
