摘要： An optical fiber structure having a holey fiber arranged in a holey outer support structure made up of holey tubes encased in a thin walled outer jacket. The holey fiber may have a solid core surrounded by a holey cladding having a plurality of rings of holes. With the invention it is possible to produce robust, coated and jacketed fibers with microstructured core features of micrometer size relatively easily using existing fiber fabrication technology. This improvement is a result of the outer holey structure which reduces the thermal mass of the supporting structure and makes it possible to reliably and controllably retain small hole features during the fiber fabrication process.

摘要： A detection apparatus arranges a light source, a curved surface prism having a curved surface and a plane surface, a metal film placed on the plane surface of the prism to be held adjacently to a test sample, and a reflecting member for reflecting light such that light emitted by the light source enters the prism through the curved surface and is reflected by the metal film, then by the reflecting member, and again by the metal film. The detection apparatus is adapted to detect an optical change in the test sample by means of surface plasmon generated on the metal film. In the detection apparatus, divergent light is made to enter the prism through the curved surface to collimate the incident light by means of the curved surface. The apparatus can suppress the broadening of the resonant bandwidth so as to operate as a monitor with a higher degree of precision.
