This coupler uses optical crystals as elements for polarization composition and separation.
This coupler is developed as a compact and high-performance fiber type module for polarization composition and separation. This product has a parallel fiber I/O structure and can be conveniently used for composition of LD light for excitation in optical fiber amplifiers

 

Features
– Low insertion loss
– High extinction ratio (for polarization separation)
– Space conservation capability due to fiber I/O from one direction and compact design
