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
