For phonetic signal modulation, if the pass band range of the band pass filter ( bpf ) is 300hz - 3400hz, the anti - noise properties of laser are approximately independent of bias current and parameters of the cavity ; when the pass band range of bpf increases to a certain degree, modulating bias current and parameters of the cavity can improve the anti - noise properties of laser
對語音調制情況,如帶通濾波器的通帶范圍取為300hz - 3400hz ,則激光器的抗噪聲性能基本不依賴于偏置電流和腔內參數;當帶通濾波器的通帶范圍增大到一定程度,調整偏置電流和腔內參數可以實現半導體激光器的高抗噪聲性能。The results of numerical simulation show that for various kinds of noise without modulation the anti - noise properties and the output quality of laser can be improved by selecting appropriately bias current and parameters of the cavity
數值模擬的結果表明,對于無調制時的各種噪聲,適當選取偏置電流和腔內參數可以提高微腔半導體激光器的抗噪聲性能或激光輸出的質量。
