Optical fiber capped at end with diffractive film, and manufacturing method therefor |
摘要 |
Affords efficiently and at low cost optical fibers capped at the end with a working, tiny optically diffractive film. An optical fiber includes a diffractive film formed onto an endface thereof, or onto the endface of a collimator joined to the endface of the fiber; the diffractive film includes a transparent DLC (diamond-like carbon) layer; and the DLC layer includes a modulated-refractive-index diffraction grating containing local regions of relatively high refractive index and local regions of relatively low refractive index.
