摘要

研究了几种具有不同结构和参数的1.55 pm DFB激光器的压缩势。图2给出了在噪声抑制和限制噪声的电流注入下，1.55 pm压缩应变带劈裂面的MQW DFB激光器在室温下的强度波动测量结果。两种情况下的激光波动都超过了单噪声极限，但在安静泵浦条件下，噪声水平下降了0.7 dB。对降低压缩的多余噪声也进行了研究，发现大多数噪声的来源似乎与低K~值引起的弱纵向侧模的存在有关。

Analysis of current self-distribution induced by self-focusing filamentation in laser diode

We investigate the squeezing potential of several 1.55 pm DFB lasers with different structures and parameters. Figure 2 presents the intensity fluctuations measurements of a 1.55 pm compressively strained MQW DFB laser with cleaved facets at room temperature under noise suppressed and shot-noiselimited current injection. The laser fluctuations in both cases exceed the shot-noise limit, but a decrease of 0.7 dB in the noise level is observed under quiet pumping conditions. The excess noise that degrades the squeezing is also examined and it appears that the source of most of this noise is associated with the presence of weak longitudinal side modes resulting from a low K~ value.
