In some optical application, lens, reflector and other micro-optics components are normally needed to be assembled on optical fibers' end face. We can also process the fiber tip into a kind of lens. At present, MEISU has the first-class optical fiber lens processing technology, and we have independently developed a complete set of optical fiber lens grinding equipment, which can produce various shapes of optical lensed fiber arrays with low cost and high precision. With the optical fiber lens grinding equipment, MEISU can also test the optical spot, far-field and other parameters of the lens.

What Is Lensed Fiber Coupling Technology?

Lensed fiber coupling technology refers to a method for efficiently coupling light between two optical fibers or between an optical fiber and another light source, such as a laser diode or a waveguide. It achieves this by incorporating specially shaped lenses on the ends of the optical fibers. Lensed fiber coupling technology offers a valuable approach to optimize light transmission between optical fibers and other light sources. By utilizing microlenses, it overcomes challenges associated with traditional coupling methods, leading to improved efficiency, easier alignment, and a wider range of design possibilities for various applications.

Applications of Lensed Fiber Coupling Technology:

Optical Communication Systems: Improves light transmission efficiency in fiber optic communication networks.

Laser Diode Coupling: Efficiently couples light from a laser diode into an optical fiber for various applications like sensors and optical amplifiers.

Medical Devices: Used in medical equipment like endoscopes and biosensors for efficient light delivery and signal transmission.

Optical Instrumentation: Enhances light coupling in optical instruments used for spectroscopy, microscopy, and other analytical applications.

How Optical fiber lens Works

Optical fiber lens, is a kind of special optical fiber. It is made by grinding the tip of the fiber into the shape of a certain lens such as angle-polished, wedge-shaped, and tapered. The optical fiber lens is used to minimize the spot size, change the optical path, or transform the optical mode in the optical system.

This kind of lens can also be arranged into V-grooves to form a lensed fiber array, with customized pitch and spot size. It is normally used to align with silicon photonic chip which has smaller MFD than regular fiber. Moreover, the lensed 2d fiber array with reduced MFD can also couple the beam into chips efficiently.
