定向耦合器 in a sentence

  1. Compare to the normal rectangular waveguide , ridge waveguide has the character of broader bandwidth , smaller dimension , lower equivalent characteristic impedance , etc . because of these merits , it is used more and more widely , such as broadband ridge waveguide filter , broadband direct coupler , diplexer , frequency converter , phase shifter , ridge waveguide slot antenna array , and so on
    与普通矩形波导相比,脊波导具有工作频带宽、尺寸小、等效特性阻抗低等特点。由于脊波导本身的特点,使其得到了越来越多的应用,例如宽带脊波导滤波器、宽带定向耦合器、双工器、变频器、移相器、脊波导缝隙天线阵等等。
  2. In the design of optical system , to improve system precision , the fiber optic coupler is added to make a laser pulse circle ; in the unit of photo detection , we make a high - precision temperature compensation apd bias circuit , which allows system to abate the noise caused by temperature changer and dark current
    应变测量系统主要由光源、传感光纤、光电探测器和信号处理电路组成。在光学系统设计中为提高系统的精度采用了光纤定向耦合器实现光脉冲的循环;在光电转换单元上采用高精度温度补偿的apd偏置电路,减小了温度和暗电流带来的噪声干扰。
  3. Nonlinear directional coupler ( nldc ) is a switch used in optical network . w . s . man had studied transmission controlling with ground state soliton through nldc , it is obviously not available to used in superhigh speed network ; and mary j . potasek had studied the self - coupling with ultrashort solitons in nldc , self - coupling is difficult to control the signal transmitting . i has studied the transmission controlling with ultrashort solitons ( < 100fs ) in nldc , similarly i use a controlling pulse to control the signal pulse , it is the intensity of controlling pulse to decide the signal change its direction or not
    非线性定向耦合器( nldc )是用在光网络中的光开关器件,它主要用在全光网络中, w . s . man等研究过基态孤子在nldc中的传输控制,便于对全光网络中数据的正确传输,由于目前研究集中在100fs的超短脉冲传输特性上,显然基态孤子的特点不再适用于超高速网络; maryj . potasek等就超短脉冲在nldc中的自耦合做了研究,在光网络中自耦合任意性太大,不利于控制脉冲的传输。
  4. 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。
