Abstract
A production device and a production method for a grating-type optical component enabling formation of a variety types of FBGs using a single phase mask and an optical component made by the production method or production device for a grating-type optical component are provided. The method involves diffusing at least one of hydrogen or deuterium into an optical fiber and altering the refractive index of the optical fiber by irradiating the fiber with non-interfering UV lamp light.
