摘要： A bidirectional fiber optic system is described in which at one terminal the output radiation of a light source (LED or semiconductor laser) is coupled through a small diameter hole in the active area of a photodiode into the core of a larger diameter transmission fiber. On the other hand, radiation propagating through the fiber in the opposite direction exits from the fiber with a large numerical aperture so that most of it is incident on the active area of the photodiode and little is lost through the hole. Also described are a number of photodiode configurations for use in such a system, as well as dual photodiodes to perform both signal detection and output monitoring functions. Further described are fiber optic sensing systems for monitoring such variables as blood pressure.

摘要： A photosensitive sol-gel film containing an organometallic photosensitizer is deposited on the oxide containing surface layer of a silicon substrate. A pattern of white or ultra violet light incident to the photosensitive sol-gel film results in the unbinding of the photosensitizer from the exposed regions of the sol-gel film. A subsequent succession of first and second heating steps results in, first, the removal of the photo sensitizer constituents from the exposed regions of the sol-gel film and, second, the removal of the organic constituents from the exposed regions, resulting in regions doped with a metal oxide with non linear optical properties, such as semicondutive, etc. properties. Optical switches, couplers, waveguides, splitters, interferometers wavelength division multiplexer, Bragg gratings and more can be fabricated. A glass substrate also may be employed, instead of a silicon, in which case a separate silicon oxide surface layer is unnecessary.

摘要： A partially modified photosensitive monolithic oxide glass apparatus formed through photolithographic imaging. The apparatus may be either a volume apparatus or a layer apparatus. Both types of apparatus may be used to diffuse light in predetermined directions or shapes. The monolithic oxide glass apparatus is capable of withstanding temperatures well beyond glass transition temperatures of plastic light shaping devices and can be formed in convex or concave surfaces through conventionally molding grinding or polishing techniques and can be coated by hot-coating techniques.

摘要： A method of determining the wavelength of light transmitted in an optical fiber comprises the steps of filtering the light using a filter, and then detecting the filtered light, and then determining the wavelength of the filtered light. The filter comprises a fiber grating which is recorded in a portion of the optical fiber. The fiber grating preferably has a modulated index of refraction with a modulation amplitude that varies from a first end to a second end of the fiber grating, and a modulation period defined by a grating constant that varies from the first end to the second end of the fiber grating. The fiber grating at least partially prevents transmission of light within a wavelength spectrum, and prevents transmission of a substantially larger portion of the light at a first end of the wavelength spectrum than at a second end of the wavelength spectrum. Therefore, the wavelength of the filtered light can be determined by determining a proportion of the light which was transmitted by the filter. The proportion of light which is transmitted by the filter is preferably linearly related to the wavelength of the light.
摘要翻译：确定在光纤中传输的光的波长的方法包括以下步骤：使用滤光片对光进行滤光，然后检测滤光，然后确定滤光的波长。滤光器包括记录在光纤的一部分中的光纤光栅。光纤光栅优选地具有从光纤光栅的第一端到第二端变化的调制幅度的调制折射率，以及由光栅常数变化的调制周期，该调制周期从第一端到第二端变化光纤光栅。光纤光栅至少部分地防止波长光谱中的光的透射，并且防止在波长光谱的第一端处的光的实质上较大部分的光在波长光谱的第二端的透射。因此，可以通过确定由滤光器透射的光的比例来确定滤光光的波长。由滤光器透射的光的比例优选与光的波长成线性关系。

摘要： A fiber optic sensor for sensing the presence of an analyte has a plurality of optical fibers each of which has at least one analyte sensing segment and one or more low loss lead portion, where the optical fibers are disposed on the periphery of a fiber carrier. The analyte sensing segments may be disposed in an offset relationship to provide continuous detection over a desired distance or they may be spaced apart to provide detection at selected locations. More than one set of optical fibers with sensing segments may be combined to provide detection of multiple analytes. Multiple fiber carriers allow each segment or the grouped sets of segments to be coupled together over a distance either in offset relationship or in spaced apart relationship.

摘要： Methods and apparatus for producing an optical waveguide illuminator are disclosed. By controlling the propagation of light in the core and cladding regions of the waveguide, distributed light emission along a length of an optical fiber or along a planar waveguide surface can be achieved by varying the core/cladding refractive index ratio and introducing light scattering centers in the core.
