ABSTRACT:
Provided is an apparatus for writing Bragg gratings and a reflection unit used in the same capable of readily adjusting an incident angle of light radiated from a light source, in order to write Bragg gratings on a target object such as an optical fiber. In accordance with the present invention, it is possible to readily adjust the incident angle of light introduced into the target object using the reflection unit when the position of the target object changes or an interval between the Bragg gratings is adjusted.
