We have analyzed and experimentally demonstrated the performance of a wavelength-locked Fabry-Perot laser diode (FP-LD) with a spectrally sliced FP-LD as an external-injection optical source. A high side-mode suppression ratio exceeding 30 dB was obtained, and the noise characteristic of the wavelength-locked FP-LD was analyzed in terms of both mode partition noise and interferometric noise. The measured relative intensity noise had a minimum value of -140 dB/Hz. We also investigated the transmission characteristics such as the Q factor and extinction ratio for a 622 Mbits/s and 2.5 Gbits/s baseband digital signal.
我们分析并通过实验证明了一种波长锁定的法布里-珀罗激光二极管（FP-LD）的性能，该FP-LD以一个光谱切片的FP-LD作为外部注入光源。获得了超过30 dB的高边模抑制比，并从模式分配噪声和干涉噪声两方面分析了波长锁定FP-LD的噪声特性。测得的相对强度噪声最小值为-140 dB/Hz。我们还研究了622 Mbits/s和2.5 Gbits/s基带数字信号的传输特性，如品质因数和消光比。
