ABSTRACT:
The present invention is directed to an optical coupler, only formed by a plurality of all plastic fibers, and a method of producing the same. Two all plastic fibers each of which has a core are placed in contact with each other over a predetermined length. Ultrasonic vibration is applied to a contacting portion of the all plastic fibers so as to bond the cores with each other at the contacting portion. Thus, the optical coupler with a low-excess-loss can easily be produced.
