Optical fiber thermal expansion technology - optical fiber mode field plastic surgery knife
In recent years, optical fiber thermal expansion technology has been more and more widely used in the field of optical passive devices. This technology is an effective way to change the fiber mode field diameter By heating the dopant ions in the fiber, the diameter of the fiber mode field is enlarged without changing the cladding diameter of the fiber.
It works like a scalpel in a surgery to change one’s face. The thermal expansion core technology can customize the mode field diameter of the optical fiber, so that the two optical fibers that are difficult to couple and dock can be easily docked. It is based on this capability that thermally expanded core fibers have been widely used in the field of optical passive devices.
ORTE Photonics Thermal expansion technology is Hydrogen-oxygen flame heating core expansion technology. It fully meets the requirements of expanding the mode field diameter of the fiber, and the water vapor generated by combustion has no pollution, no residue, and no impurities are introduced into the fiber. It is an ideal thermal core expansion technology which is widely applied in most of ORTE photonics series, such as optical hybrid, optical isolator, CCWDM、TAP PD,MCF Fan-in & Fan-outs.
