Features

Fiber-to-fiber coupler with one integrated wave plate / retardation optics
  • For single-moder or PM fiber cables
  • As an option input polarizer
  • adjustable halfe-wave plate or quarter-wave plate
  • Compact, rugged, transportable and sealed opto-mechanical units
  • Very high long-term stability, efficiency and reproducability
  • Can be used as interface between different types of single-mode fibers or connectors

Description

The fiber-to-fiber coupler type 48-MCS-025 is equipped with an addition integrated wave plate / retardation optics.

Polarizer
As an option the system can be equiped with an input polarizer.

Wave plate
The integrated wave plate is a half-wave plate or a quarter-wave plate. A selection of wave-plates available on stock can be found here. Dual wavelengths wave plates or achromatic wave plates are available on request.

Fiber couplers
A fundamental component of the Fiber-to-Fiber Coupler is the Laser Beam Coupler, which is the input into the opto-mechanical unit collimating the input radiation and, finally, couples the radiation back into the second fiber cable. The stability of the total Fiber-to-Fiber Coupler is determined by the stability of the laser beam coupler.

Depending on the choice of lens type (monochromatic or achromatic) within the Laser Beam Couplers, the system can either be used for a single wavelength or for a wavelength range.

Coupling focal length
The best focal length for the 60SMS Laser Beam Couplers used in these systems is f' 11 - 12 mm. If the effective numerical apertures of the two fiber used with this system are different, you have to use two Laser Beam Couplers with different focal lengths.

Configuration
For selecting the 60SMS Laser Beam Couplers please refer to the 60SMS Laser Beam Couplers site.
