Abstract
An optical device,comprises an input optical member,, in which a plurality of optical fibers,are arranged parallel to each other and integrally formed, having an entrance surface,and an exit surface,which intersect an optical axis at respective angles of 90° and 20°; and an output optical member,, in which a plurality of optical fibers are arranged parallel to each other and integrally formed, having an entrance surface,intersecting an optical axis at an angle of 55° and an exit surface,parallel to the entrance surface,. Here, the exit surface,of the input optical member,and the entrance surface,of the output optical member,are in contact with each other, whereas the angle formed between the optical axis of the input optical member,and the optical axis of the output optical member,is an angle of 35° which is the difference between 55° and 20° mentioned above.
