Polarization-preserving fiber arrays are an important component in interferometric fiber sensors based on optical coherence detection.

     Our polarization-preserving fiber arrays are divided into two series: one-dimensional linear array and two-dimensional surface array. These two series are made of silicon-based aperture plates, which are characterized by high alignment accuracy and no cumulative error, and can transmit the polarization-preserving signal in the surface array. On the premise of high throughput, high density and high precision transmission, the polarization state of light will not change during the transmission of light waves, which reduces the interference of light transmission, improves the coherent signal mania ratio and stability, and realizes the high precision measurement of physical quantities. 

     It is mainly used in optical fiber sensors, communication systems, test instruments and other fields.
