Polarization Composition/Separation Coupler
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
