(760~850nm) 大芯径多模光纤拉锥耦合器

Category:MFBT-7685-26Nv011
Code:大芯径多模拉锥光纤耦合器

XYT-MFBT-D760~850  

【NO.】MFBT-7685-26Nv011

大芯径多模光纤拉锥耦合(760~850nm)  

产品叙述

两光纤波导之间的耦合,在熔锥区两光纤包层合并在一起,纤芯足够逼近,形成弱耦合,相耦合的两波导中的场,各自保持了该波导独立存在时的场分布和传输系数,耦合的影响表现在场的复数振幅的沿途变化。两光纤耦合光功率分配,P1(z)=直通臂光功率;P2(z)=耦合臂光功率;Z=拉锥长度,C为耦合系数;F2=最大耦合比。
