Lensed fiber is a precision optical fiber with a specially shaped tip designed to improve optical coupling efficiency in photonic systems. 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 fiber optic 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.

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.

What is a lensed fiber?
A lensed fiber is an optical fiber with a specially shaped tip used to improve optical coupling efficiency.
What is the purpose of a fiber lens?
To match optical modes between devices and reduce coupling loss.
What are the types of lensed fiber?
Angled, wedge, spherical, and conical fiber lenses.
How does a lensed fiber improve coupling efficiency?
By optimizing beam divergence, spot size, and mode field matching.
What is the difference between lensed fiber and standard fiber?
Standard fiber emits a divergent beam, while lensed fiber controls beam shape for better coupling.
Where are lensed fibers used?
Silicon photonics, optical communication, VCSEL coupling, OCT systems, and sensing.
Can lensed fibers be customized?
Yes, including geometry, working distance, coating, and fiber type.
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 fiber array with reduced MFD can also couple the beam into chips efficiently.
