摘要

As shown in Fig. 1, an optical device 10 comprises an input optical member 11, in which a plurality of optical fibers 14 are arranged parallel to each other and integrally formed, having an entrance surface 11a and an exit surface 11b which intersect an optical axis at an angle of 15 DEG and at an angle of 30 DEG , respectively; and an output optical member 12, in which a plurality of optical fibers are arranged parallel to each other and integrally formed, having an entrance surface 12a and an exit surface 12b which intersect an optical axis at an angle of 7.5 DEG and at an angle of 90 DEG , respectively. Here, the exit surface 11b of the input optical member 11 and the entrance surface 12a of the output optical member 12 are in contact with each other, whereas the angle formed between the optical axis of the input optical member 11 and the optical axis of the output optical member 12 is an angle of 22.5 DEG which is the difference between 30 DEG and 7.5 DEG mentioned above.
