Hollow core anti-resonant fiber 200-3500nm (core diameter 33um, cladding 250um, pure quartz material)

Silica fiber has been widely used in various scenarios for laser transmission, but in many fields, due to the nonlinear effects caused by the material, the light guide window, the damage mechanism of the laser to the fiber material, etc., the laser transmission based on quartz has basically reached the limit of the fiber. Anti-resonant fiber (ARF) is a hollow-core fiber in which light can be confined to the hollow with a refractive index less than that of the fiber material and transmitted along the fiber axis. Hollow fiber has extremely low nonlinearity, high damage threshold, and small overlap between the internal transmission beam and the surrounding glass, which provides a unique possible solution for fiber-based, very high-power lasers. This will achieve breakthrough applications in laser manufacturing, laser ignition, defense, ultrafast lasers, nonlinear endoscopes/microscopes, and gas-based mid-infrared lasers.

Polyimide coated high temperature resistant single mode optical fiber SM9/125/155PI

Polyimide is a polymer material with good high and low temperature resistance, good mechanical strength, and excellent comprehensive performance. It can greatly improve the heat resistance of the optical fiber coating layer, extend the service life of the optical fiber in a high temperature environment, and at the same time maintain good mechanical properties in a low temperature environment without brittle cracking. Polyimide is a self-extinguishing polymer with a low smoke rate and a thermal expansion coefficient close to that of quartz. It has certain self-lubricating properties, is resistant to aging, and is resistant to high-voltage electrical breakdown. It has very little outgassing under high vacuum. Polyimide has high radiation resistance and mechanical properties, and can still maintain high strength under irradiation. It has high tensile, bending, and compression strengths, and outstanding creep resistance and dimensional stability. Polyimide is non-toxic, stable, and biocompatible, and can be used to prepare tableware and some medical consumables replacement supplies. At the same time, polyimide is resistant to almost all organic solvents, some inorganic acids, and hydrolysis

600um large core energy transmission optical fiber

We are currently able to provide international commercial-level quartz energy optical fibers in batches. Our energy optical fibers include two categories: quartz cladding type high-performance energy optical fibers and plastic cladding type high-performance energy optical fibers. Quartz cladding type energy optical fibers can transmit higher laser power, have good resistance to optical damage, as well as lower attenuation and higher light transmittance (from near ultraviolet band to near infrared band 400nm ~ 1600nm).

1550nm Single-Mode Fiber Reflector

Examples of fiber total reflection mirrors used in erbium-doped fiber amplifiers. In this application, a fiber-based back reflector is placed at the end of an erbium-doped fiber, reflecting light back into the fiber in the direction of the incident light. A circulator is used to direct both the input and amplified output signals along their respective optical paths. This setup allows the signal light to pass through the gain fiber twice, effectively enhancing the amplifier's gain absorption efficiency. Another practical application of back reflectors is the construction of tunable back reflectors, as shown in Figure Feedback signals from a downstream back reflector can cause instability in certain devices, such as laser diodes. By incorporating a tunable back reflector, the sensitivity of a device to back reflection can be determined. A tunable attenuator enables users to introduce a controlled reflection into the system. By analyzing the effects of back reflection, users can calculate parameters such as noise level, bit error rate, and distortion.

1310nm 1X4 Polarization Maintaining Fiber Coupler Module

Idealphotonics’ low-profile couplers have inherent performance advantages because the waveguide core is not deformed or tapered. These devices have low losses and back reflections. Also, the short interaction length (1-2 mm) allows for small device packaging. The interface is essentially vanishing in optical contact between identical silica surfaces. There is no intermediate material that changes its refractive index or thickness with age or environmental influences. The optical performance of the couplers is as if the fibers were molten and is very stable under temperature variations. The fibers are side-polished in a glass substrate block to remove the cladding material on one side of the core without distorting the core region. For PM fibers, only one stress member remains. The two polished fibers are brought into optical contact with their polarization axes aligned and coupling between the cores is achieved by the evanescent wave interaction. Precise loading of the substrate block ensures that the fibers remain in low-stress contact over a wide temperature range.
