| 摘 要： | 计算了相位调制器光谱展宽与调制深度的关系，分析并通过实验观察了０．６３２８μｍ光辐射在功率１Ｗ，２．４５ＧＨｚ微波驱动下的频谱，推得调制深度与微波功率的表达式。最后用光栅谱仪测得在１６Ｗ微波功率作用下产生０．１３ｎｍ光谱宽度，两种测试结果吻合较好。

| Abstract: | The relation of spanned optical spectrum and modulation intensity in a phase modulator is calculated in this paper. The frequency spectrum of 0.6328 μm light driven by 2.45 GHz microwave at 1 W power is analyzed and observed. Finally, with a grating spectrometer, the 0.13 nm spectrum width at 16 W microwave power is measured. The two measured results are in good agreements. |
