Japanese Patent JP2854943
Kind Code:
B2
Abstract:
The present invention is directed to an optical coupler, only formed by a plurality of all plastic fibers (10,11) and a method of producing the same. Two all plastic fibers (10,11) each of which has a core (10a,11a) are placed in contact with each other over a predetermined length. Ultrasonic vibration is applied to a contacting portion of the all plastic fibers (10,11) as to bond the cores (10a,11a) with each other at the contacting portion. Thus, the optical coupler with a low-excess-loss can easily be produced.
