Study on the directional couper in the active optical switch
有源光开关中的方向耦合器研究
L-band design of big power stripline direction couper
L波段大功率微波带状线定向耦合器的设计
The output band stop characteristics of the fiber optic ring resonator ( FORR ) are theoretically derived in consideration of additional phaseshift induced by loss of the couper .
