Examples
- At present , signal pulses produced by directly modulated laser diodes have been used in optical fiber communication systems . the experiment reveals that the optical pulses from directly modulated laser diodes are far from gaussian and have near - rectangular temporal profiles with much sharper leading and trailing edges , and then a super - gaussian model , which assumes that an incident optical pulse has a super - gaussian profile , may be more suitable
但在实际的光通信系统中，人们常采用由直接调制半导体激光器产生的光脉冲作为信号脉冲，而实验结果表明这种脉冲具有比高斯脉冲更为陡峭的前沿和后沿，其脉冲形状更接近于超高斯分布，并且通常还带有一定量的啁啾。
