We propose a novel fiber alignment method using a partially metal-coated (PMC) fiber. A PMC fiber is a fiber whose side is partially metal coated, and a core of PMC fiber can be regarded as eccentric with respect to the outside of PMC fiber. Rotating the PMC fiber in a silicon V-groove, the core position can be aligned. Using this method, laser diode modules with high coupling efficiency were obtained.
