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
但在實際的光通信系統中，人們常採用由直接調制半導體激光器產生的光脈沖作為信號脈沖，而實驗結果表明這種脈沖具有比高斯脈沖更為陡峭的前沿和后沿，其脈沖形狀更接近於超高斯分佈，並且通常還帶有一定量的啁啾。
