Our high-precision 2D Fiber Array is equipped with microlens array made by advanced lithography process, each fiber is individually coupled with a microlens in front, thus realizing the combination of fiber array and microlens with high density, high precision, miniaturization and integration. The 2D fiber array with microlens array has better light gathering, collimation and other functions. Facilitates users to achieve coupling of spatial light or calibration of light source beams; effectively reduces the valuable chip volume required for optical input/output; also provides spot size conversion between small cross-section, chip-based waveguides and standard fibers. Realizing high-capacity, multi-channel parallel or individual processing of information, it is widely used in optical sensing, optical computing, fiber optic communication and other optoelectronic devices.
