LIGHT GUIDING DEVICE, MANUFACTURING METHOD, AND LD MODULE

摘要

A double mirror (Mi) of a light-guiding device of the present invention is made of (i) a first mirror (Mi1) that is mounted on a top surface of a base plate (B) and has a reflective surface (S1) entering an input beam reflected by the reflective surface (S1) and (ii) a second mirror (Mi2) that is mounted on a top surface of the first mirror (Mi1) and is a prism having a reflective surface (S2) reflecting the input beam that has been reflected by the reflective surface (S1), the input beam reflected by the reflective surface (S2) being totally reflected inside the prism.

主权项

1. A light-guiding device that converts an input beam bundle made of a plurality of input beams to an output beam bundle made of a plurality of output beams, comprising:
double mirrors each corresponding to a corresponding one of the input beams, the double mirrors each being separated from the other double mirrors each corresponding to another one of the input beams, the double mirrors respectively corresponding to the input beams each being made of a first mirror that is mounted on a specific flat surface and a second mirror that is mounted on the first mirror, the first mirror having a first reflective surface reflecting a corresponding one of the input beams, the second mirror having a second reflective surface reflecting the corresponding one of the input beams that has been reflected by the first reflective surface, the second mirror being a prism, the corresponding one of the input beams reflected by the first reflective surface being reflected outside the first mirror, the corresponding one of the input beams reflected by the second reflective surface being totally reflected inside the prism.
