Abstract

PURPOSE:To eliminate the lens and miniaturize the whole circuit by forming one end face connected to the other optical fiber to be an oblique face to the axis, and ing the oblique angle such that a portion of the passing light is rendered to reflect it in order to introduce it to the outside in a simple configuration.
