A method for manufacturing an all-fiber device. The method comprises the following steps. First, a recess with a predetermined radius is formed on a semiconductor substrate. A first optical fiber is then fixed in the recess by an adhesive. Subsequently, a cladding layer of the first optical fiber is polished to form a first side-polished optical fiber with a first polished surface near a core region of the first optical fiber. Then, the first optical fiber is separated from the semiconductor substrate by a liquid. Like the first side-polished optical fiber, a second side-polished optical fiber with a second polished surface is formed. Finally, after the first polished surface is aligned and in contact with the second polished surface, the first side-polished optical fiber and the second side-polished optical fiber are fused to form the all-fiber device. A coupling region is formed between the first and second polished surfaces.
