宽带器件 meaning in Chinese

broadband device

The wavelength dependence of the directional couplers is modeled and with this model optimal designs of planar wavelength circuits based on mach - zehnder interferometers and their cascaded forms are presented . liquid crystals are widely used in optical information processing technologies . optical devices based on liquid crystals , such as variable optical attenuators ( voas ) , switches and tunable filters , have been introduced into the area of optical communications recently
在基于级联mach - zehnder干涉仪的宽带器件设计中，本论文建立了定向耦合器波长敏感性的近似模型，并在此基础上提出了通过对初始结构(即不考虑定向耦合器波长敏感性的设计结果)做微扰来确定宽带器件结构参数的设计方法。
