Australian Polarization-Maintaining Fiber Coupling System

The Polarization Maintaining Coupler is a micro optic filter type device that provides optical signal splitting while preserving polarization with high ER. They are constructed by fusing and tapering the fibers together. This method creates a simple, rugged, compact method of splitting or combining. The defined interface between a laser source and the more sensitive environment of the measurement setup provides the physical separation that enables a mechanical and thermal decoupling, suppressing mutually negative effects. But first decisions have to be made about which components to use. The increasing use of polarization maintaining fiber at the initiation point of signals is driving demand for polarization maintaining laser diode-to-fiber couplers. [pdf]
