440nm high-power large core diameter multimode fiber splitter (wavelength range 400-633nm)

The VIS-MFC-LMA series large core fiber coupler is a coupler developed and produced based on our company's single-mode fiber fusion taper machine IPCS-5000-LMA for visible light band splitting. It has excellent performance and is different from multimode fibers (50/125, 62.5/125) widely used in fiber communication systems. Large core fiber is usually used to transmit larger laser power and special working bands. Meanwhile, due to the characteristics of large fiber core diameter and high numerical aperture, the uniformity and stability of light splitting in large core fiber are affected by various factors (such as laser mode, laser injection method, etc.). Based on years of experience in high-energy laser transmission experiments and research on the reliability of military Yong devices, we are now able to provide fiber optic splitter products with core diameters ranging from 125um to 1500um, as well as large core fiber optic splitter products that operate at all wavelengths. These products have extremely high resistance to high-power laser impact and high environmental reliability. Since its establishment, the company has continuously invested in research and development efforts to optimize and improve the melting process and product packaging process of special large-diameter fiber optic splitters. In the process of product miniaturization and one-time melting of multi-core optical fibers

Polarization maintaining fiber coupler module 1310nm/1550nm

Xiaoxiao Photon's low frequency local coupler has inherent performance advantages because the waveguide core does not deform or gradually become thinner. These devices have low loss and backward reflection. Moreover, the shorter interaction length (1-2 millimeters) allows for the encapsulation of small devices. The interface basically disappears in optical contact between the same silicon dioxide surfaces. No intermediate material will change its refractive index or thickness with age or environmental influences. The optical performance of the coupler seems to be that the fiber is melted and very stable under temperature changes. Polish the fibers on the side of the glass substrate to remove the cladding material on one side of the core without distorting the core area. For PM fibers, there is only one stress component left. Make optical contact between two polished optical fibers with their polarization axes aligned, and achieve coupling between the fiber cores through the evanescent wave interaction. The precise loading of the substrate ensures that the fibers maintain low stress contact over a wide temperature range.

Polarization maintaining fiber combiner/splitter 532nm/1064nm/1310nm/1550nm

Xiaoxiao Photon Fusion Fiber Polarization Beam Combiner/Divider is used to couple two orthogonal polarized light beams into one fiber, or separate an input light beam into two orthogonal linearly polarized light beams for output. These devices are fully operated through fiber optics; Polarization states are combined or separated through fused fiber optic nodes. Compared with polarization beam combiners based on calcite prisms, this all fiber structure can achieve higher transmission rates and withstand higher power. Due to the fact that the polarization maintaining fiber in the molten fiber polarization beam combiner does not serve as a polarizer, the input light must be linearly polarized and aligned with the fast and/or slow axes of the fiber. These devices are highly suitable for coupling the light from two pump lasers into a single fiber to enhance the input light of erbium-doped or Raman fiber amplifiers.

1x2/2x2 polarization maintaining fiber coupler (400-2000nm)

These 2x2 polarization maintaining (PM) fiber couplers are designed for 460-2200 nm, with selectable coupling ratios of 50:50, 75:25, 90:10, or 99:1. The 2x2 couplers are bidirectional and can be used for separating and mixing signals (see 2x2 coupling example label). Polarization maintaining couplers are made using panda shaped polarization maintaining fibers, so they can maintain a high polarization extinction ratio (PER) when light is emitted along the slow axis of the fiber. As shown in the figure on the right, the stress rod is parallel to the fiber core and applies stress, generating birefringence in the fiber core to achieve polarization maintenance. Typical applications of polarization maintaining couplers include optical sensors, optical amplifiers, and fiber optic gyroscopes. The default alignment method for Xiaoxiao Photon's optical polarization maintaining components is slow axis alignment. Xiaoxiao Photon's polarization maintaining coupler has a high extinction ratio and can operate over a wide temperature range of -40 ° C to 85 ° C. Note that PER will vary with temperature; For details, please refer to the temperature cycling test section in the polarization extinction ratio measurement label. They have Max with connectors or bare fibers The power is 1 W, and during welding it is 5 W (please refer to the damage threshold label for details). These couplers have undergone extensive testing and PER validation
