A method of 90゜optical path conversion is a key of Optical Surface Mount Technology (O-SMT) which was proposed to provide a possible solution for growing serious problems in manufacturing process of opto-electronic products. We have proposed a new method that can change the optical path from the vertical to the horizontal using an optical pin with a micro mirror. An optical pin was fabricated by cutting a multi-mode fiber at 45゜. We studied reflection characteristics of an optical pin with a micro mirror and found that the optical ray component which leaked through the 45゜mirror existed. The insertion loss between a polymeric optical waveguide and an optical pin with a micro mirror was measured to be 30%. It is clarified that an optical pin with a micro mirror has a useful function of changing the beam direction from the vertical to the horizontal and vice versa.
