    1270nm to 1610nm or 1550nm Fiber Bragg Grating FBGs

    1270nm to 1610nm or 1550nm Fiber Bragg Grating FBGs are a kind of diffraction grating formed by periodically modulating the refractive index of the core of the fiber through a certain method. It is a passive filter device. Grating fibers are widely used in the fields of optical fiber communication, optical fiber sensing and optical fiber signal processing because of their small size, low fusion loss, full compatibility with optical fibers and embedded intelligent materials, and their resonant wavelength is sensitive to the changes of temperature, strain, refractive index, concentration and other external environment.

  • fiber-optic laser

    Fiber lasers use rare-earth-doped fiber as the gain medium, and the pump light forms a high power density in the fiber core, causing the "population inversion" of the doped ion energy level. When a positive feedback loop (forming a resonant cavity) is properly added, It produces laser output.

  • Short wavelength narrow linewidth fiber laser

    For spectral synthesis technology, increasing the number of synthesized laser sub-beams is one of the important ways to increase the synthesis power. Expanding the spectral range of fiber lasers will help increase the number of spectral synthesis laser sub-beams and increase the spectral synthesis power [44-45]. At present, the commonly used spectrum synthesis range is 1050～1072 nm. Further expanding the wavelength range of narrow linewidth fiber lasers to 1030 nm is of great significance to the spectrum synthesis technology. Therefore, many research institutions have focused on short wavelength (wavelength less than 1040 nm) narrow line Wide fiber lasers were studied. This paper mainly studies the 1030 nm fiber laser, and extends the wavelength range of the spectrally synthesized laser sub-beam to 1030 nm.

  • Fiber Optic Gyro

    Fiber optic gyroscope is the fiber angular velocity sensor, which is the most promising one among various fiber optic sensors. The fiber optic gyroscope, like the ring laser gyroscope, has the advantages of no mechanical moving parts, no warm-up time, insensitive acceleration, wide dynamic range, digital output, and small size. In addition, the fiber optic gyroscope also overcomes the fatal shortcomings of ring laser gyroscopes such as high cost and blocking phenomenon. Therefore, fiber optic gyroscopes are valued by many countries. Low-precision civilian fiber optic gyroscopes have been produced in small batches in Western Europe. It is estimated that in 1994, the sales of fiber optic gyroscopes in the American gyroscope market will reach 49%, and the cable gyroscope will take the second place (accounting for 35% of sales).

  • Outline of Polarization Fiber and Several Problems in Practical

    When using laser as a carrier wave for communication or tools for processing, medical treatment, sensing, and detection, it is usually necessary to manage the polarization state of the laser. If the system needs to maintain a certain special polarization state of the laser, in the case of non-free space, the polarization-maintaining fiber or the circular-preserving fiber will be a practical solution to maintain the laser polarization state in a closed channel mode.
