Fiber Array, referred as to: FA. The optical coupling component that is between the optical waveguide and the devices. Using sophisticated optical fiber assembly process to reach accurate positioning so that thermal expansion coefficient matching assembly designed to ensure the fiber array base plate no stress. After 200 hours of high and low temperature reliability experiment, accurate port plane angle, align the chip accurately; and polish plane comes bright and clean. Vsunlight self-produced fiber array provides a variety of options, such as the channelnumber of fiber array, core spacing and grinding angle. It is widely used in planaroptical waveguide (PLC), arrayed waveguide grating (AWG), Active array opticaldevices in different fields such as MEMS and so on .
