Basic Overview of Polarization-Maintaining Fiber Splitter
Let me introduce you to the basic overview of polarization-maintaining fiber splitter:
Definition and structure:
- Polarization-maintaining fiber splitter is an optical splitter that uses polarization-maintaining fiber as a transmission medium
- It consists of polarization-maintaining fiber and special polarization separation elements
- By introducing stress or geometric anisotropy in polarization-maintaining fiber
- The two orthogonal polarization modes of light produce different propagation constants
- At the input end, the input light is separated into two orthogonally polarized output lights
Introduction to working principle:
- Polarization-maintaining fiber splitter can accurately separate the input polarized light into two orthogonally polarized lights
- This is achieved through the anisotropy of polarization-maintaining fiber and special polarization separation elements
- The two orthogonal polarized lights output can maintain good polarization characteristics and transmit independently
Difference from ordinary optical splitters:
- Ordinary optical splitters are isotropic and cannot control the polarization state
- The polarization state of the output light will change randomly and cannot be predicted
- And the polarization-maintaining fiber splitter can stably separate the orthogonal polarization output light
- This precise control of the polarization state of light is the unique advantage of the polarization-maintaining fiber splitter
In short, the polarization-maintaining fiber splitter uses the anisotropy of the polarization-maintaining fiber to achieve precise separation and control of the polarization state of the light wave, which is essentially different from the ordinary optical splitter. This unique function makes the polarization-maintaining fiber splitter play an important role in some professional applications with strict requirements on polarization.
