Fused Coupler: Best Polaroid Filter for Maintaining Light Polarization

Achieving polarized light is very crucial and the quality of end results highly depends on the precision in maintaining polarized light. So it is very important to carefully choose the Polaroid filter that helps you achieve polarized light perfectly. And Fused Coupler would make the best choice for you.

 Let us take a snap look at the polarization

Light is a type of electromagnetic wave, consisting of oscillating electrical fields called as E, and magnetic fields, called B. Light waves go in many directions and when the light goes in different directions this means the light is unpolarized. But when it is vibrating one single direction, the light is polarized. A certain device that is used to polarize the light is called coupler or Polaroid filter which comes in different types and make like fused coupler most widely used for polarization maintaining.

What is polarization maintaining fiber and how does it work?

 It is kind of single mode fiber used to balance the direction light, and is available in various capacities. The normal single mode fiber is efficient enough to carry randomly polarized light. Yet, PM fiber is intended to do only one polarization of the input light.

 In the polarization maintaining fiber, the polarization of linearly polarized light waves which is launched into the fiber is maintained at the time of propagation. But there is no cross-coupling of optical power between the polarized modes. The coupler with this feature is extremely important for the some kinds of optical components, for example, external modulators that require a polarized light input.

So it is crucial to buy a coupler that helps you achieve the kind of polarization you need. If you are looking for the polarization fiber that can help you can achieve linear polarization without any no cross-coupling of optical power between the polarized modes, get fused coupler that is  built using  unique fusing technique and polarization maintaining fiber to build the 980/1030/1064nm polarization maintaining fused coupler (PMC). And you can achieve the coupling ration according to your requirement.

Low excess loss, small size and high polarization extinction ratio are what make the fiber a great option for optical sensors and optical gyro. In addition, it has many more features such as:

  • Low Insertion Loss
  • High Extinction Ratio
  • Compact In-Line Package
  • Available for Slow or Fast Axis Operation
  • High Stability and Reliability

The PM Fused Coupler can also be used to split high power linearly polarized light into multiple paths without interfering to the linear state of polarization. The coupler is also used a power control point to monitor the signal power in a PM fiber system. Given the cutting-edge features, fused coupler is widely used for different components requiring light polarization. The fiber can be used for

  • Fiber Optic Instruments
  • Fiber Amplifiers
  • Fiber Sensors
  • Coherent Detecting
  • Research
