| Single Mode Polarization Independent Couplers --PIC-1¡Á2, 2¡Á2 |
¡¡The polarization independent couplers
can be used to split light from one fiber to two or combine light
from two fibers to one and provide high performance across a broad
wavelength region. PIC couplers have the low polarization dependent
loss and low insertion loss. |
