Abstract
A multi-channel laser device with a fiber array includes a housing and a ferrule. In the housing, laser components are arranged side by side, and each of the laser components is connected to a fiber array module through an optical isolator. The fiber array module includes thermal expanded fibers, and fibers out of the fiber array module are collected by the ferrule. The laser components are disposed on the same module board, and laser light radiated from the front end of a laser chip in each of the laser components is projected onto the optical isolator through a convex lens and then enters into the thermal expanded fiber. Such a structure may reach a relatively-high coupling efficiency and implement the coupling of arrayed laser components.
