    摘要： The present disclosure provides an optical detector for detecting radiation. The optical detector includes an optical light guide that incorporates a sensing region. The sensing region includes a sensing material that emits luminescence light when the sensing material is exposed to suitable ionizing radiation and accrues trapped charge which is released and produces optically stimulated luminescence (OSL) when the sensing material is optically stimulated. The optical detector also includes a light source for optically stimulating the sensing material and a light detector for detecting the OSL. The optical light guide is arranged to guide light through the sensing region and between the sensing region and the luminescence light detector.

    摘要： An integrated-optic sensor includes a waveguide made from a substrate that is doped with rare-earth elements. A beam of light propagating along the waveguide excites these elements, causing them to emit light and thereby increase the total amount of light being propagated in the waveguide. The waveguide itself functions as a laser, so that any change in an optical property of an analyte material which forms a portion of the laser cavity can affect the operation of the laser. Consequently, the wavelength or power of light produced by the laser changes, in direct response to changes in the concentration of a material being sensed, and these changes are enhanced due to the inherent gain characteristics of the laser media.

    摘要： An optical fiber amplifier includes a laser pump source for generating laser pump light; a fiber including an inner cladding layer optically coupled to a laser pump source for receiving laser pump light; a large mode area (LMA) core surrounded by the inner cladding, the LMA core including a confined region having a predetermined doping concentration of rare-earth ions for undergoing excitation to generate laser light when pumped by the laser pump light; and an outer cladding layer surrounding the inner cladding layer for substantially confining the laser pump light to the inner cladding and the LMA core. In a method of forming the optical fiber amplifier, a ratio of an area of the confined region to an area of the LMA core, and the predetermined doping concentration of the rare earth ions are selected so as to achieve a quantum efficiency (QE) gain factor of approximately 2, but such that the heat dissipation per unit length can be controlled by adjusting the area of the confined region.
