title: Optical fiber long-period gratings with Langmuir-Blodgett thin-film overlays.
abstract: An overlay material was deposited by the Langmuir-Blodgett technique onto a single-mode optical fiber containing a long-period grating. The long-period grating exhibits characteristic attenuation bands in its transmission spectrum whose central wavelengths were observed to depend on the optical thickness of the overlay material, even for materials that have a refractive index higher than that of silica.
