中红外硅波导拉曼激光器的理论分析

In this paper, the possibility of the Mid-IR silicon waveguide Raman laser is shown by numerically calculating the the transfer equations of the extracavity Raman laser. If the pumping wavelength is 2.94 μm, the output Raman laser at 3.47 μm can be obtained with the 521 cm-1 Raman shift. The characteristics of the F-P cavity and ring cavity Mid-IR silicon waveguide Raman lasers are analysed. For the F-P cavity Mid-IR silicon waveguide Raman laser, when the effective mode area is 5 μm2, the waveguide wavelength is 30 mm, and the linear loss is 0.5 dB/cm, the laser threshold is obtained to be less than 1 W. The output properties of the two Mid-IR silicon waveguide Raman lasers are calculated and discussed under different conditions.
