Meantime, the diffraction efficiency of the BSG is discussed based on rigorous coupled-wave theory. 研究發(fā)現，在占寬比和槽深這兩個(gè)光柵結構參量中，槽深的變化對衍射效率更敏感。
In summary, the experimental results confirm the applicability of QWIPs with grating structure for normal incident light coupling and the tunable response shape. 所以利用光柵結構我們制作出可以正向入射的紅外線(xiàn)偵測器，而且響應的波形可以利用光柵的繞射耦合來(lái)調變。
