Polarization Composition/Separation Coupler

Polarization Composition/Separation Coupler (Parallel Type)

Lasermate offers the polarization coupler using optical crystals as elements for polarization composition and separation. This polarization coupler is developed as a compact and high-performance fiber type module for polarization composition and separation. It 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

Typical Specifications

Model	POC- Series
Insertion Loss	< 0.7 dB
