Base on this structure, the photoresponse of each spectral shape is tunable by the period of gratings.

我们可以利用各种不同周期光栅结构来调变。

A new dynamic model is developed for simulating the widely tunable grating assisted codirectional coupler with rear sampled grating reflector (GCSR) lasers.

提出了一个新分析模型，用于宽带可调谐GCSR激光器动态特性模拟。
