三角形光脉冲在时域范围内具有前后沿恒定变化特性,使得其在全光信息处理领域获得了广泛应用。主要针对目前国内外提出的两类三角形光脉冲产生方法:(1)电光法;(2)全光法,简单介绍了几种具体的获得稳定三角形光脉冲串的方法,从所产生三角形脉冲的重复频率、脉冲宽度以及系统稳定性、实验优缺点等方面进行分类比较,并重点介绍了一种利用连续波光调制结合色散所致功率衰落的脉冲生成方法。
Triangular optical pulse is widely used in all-optical information processing for linear upping and falling edges in time domain. According to two methods, such as electro-optical and all-optical method of triangular pulse generation in China and foreign countries, the detailed methods of obtaining stable triangular optical pulse train are introduced briefly. The repetition frequency and pulse width of the generated triangular pulse, system stability and the advantages and disadvantages of the experiment are compared classifiablv. And a pulse generationmethod resulting power fading using continuous wave modulation with dispersion is introduced.
