    摘要: A fiber optic temperature sensor (10) and system employ optical (fiber 34) and a fiber Bragg grating (36) using non-silica materials that can withstand temperature ranges extending well above the silica-imposed limit of 1,100 degrees C. The system measures the wavelength shift of light reflected from the fiber Bragg grating (36) and converts it into a temperature value. Specific optical fibers include sapphire, which can be used at temperatures approaching 1,800 degrees C., and yttria-stabilized zirconia (YSZ), which can be used at temperature in excess of 2,300 degrees C. One specific grating employs alternating layers of YSZ, with the percentage of yttria varying in the alternating layers to achieve the desired difference of refractive index, and another grating employs alternating layers of alumina and zirconia.

    摘要: Dynamically generating a wrapper object to intercept transmissions between a vendor object and an application program and performs server side tasks. To dynamically generate the wrapper at runtime in memory, the application server receives a vendor class, performs reflection on the vendor class, generates a wrapper class, and creates an instance of the wrapper class. In operation, the dynamically generated wrapper object receives a call placed to a method of the wrapped object, initiates pre-processing tasks to be performed, calls the method on the wrapped object, receives a result from the method invocation against the wrapped object, initiates post-processing tasks to be performed, and transmits the wrapped result back to the application program. The pre-processing tasks may include execution of a pre-invocation handler. The post-processing tasks may include execution of a post-invocation handler.

    摘要: Application of non-uniform strain to discrete segments of a fiber grating mechanically changes the structure type of the associated device, e.g., the refractive index perturbation profile of the fiber grating is changed from uniform to phase shifted superstructured, or from chirped to superstructured. The strain may be applied with one or more deformable corrugated slides which are bonded to the fiber grating between the discrete segments. The applied strain changes the local period of fiber grating. Complex changes may be achieved via variations of corrugated slide dimensions. An LPFG may be provided with bare fiber by applying periodically longitudinal axial strain to fiber at multiple discrete segments on the fiber.

An actuator applies stress to selected sections of the LPFG in order to switch a fiber laser cavity at a specified wavelength. A controller controls the application of stress in the time domain, thereby switching the Q-factor of the fiber laser cavity.

    摘要: A wireless device may receive a BA-list from a wireless service provider. Before removing any cell frequencies already stored in the wireless device, the wireless device may determine if the BA-list is complete. If the BA-list is not complete, the cell frequencies already stored in the wireless device may be retained, and the cell frequencies received in the BA-list may be added to the storage. However, if the BA-list is complete, the cell frequencies already stored in the wireless device may be removed if they are not in the BA-list.

    摘要: A Q-switched all-fiber laser utilizes a long period fibre grating (LPFG) modulator. The LPFG modulator is characterized by optical spectral characteristics that are controlled by application of stress via an actuator. In particular, the actuator applies stress to selected sections of the LPFG in order to modulate a light signal at a specified wavelength. Further, a controller is utilized to control the application of stress in the time domain, and thereby switch the Q-factor of the fiber laser cavity. In addition to the LPFG, the laser cavity comprises a pair of fiber Bragg gratings (FBGs) and a fiber gain medium.

    摘要: A tuning device for an optical fiber grating includes a multi-part confinement member. The confinement member includes a feature such as a channel in which the fiber grating is disposed. Movement of the different parts of the confinement member relative to one another causes compression or tension of the fiber grating. The confinement member may include first and second slides. One end of the fiber is bonded to the first slide, the other end of the fiber is bonded to the second slide. The grating section of the fiber is confined in a channel formed by adjacent surfaces of the slides. The dimensions of the channel are selected such that the fiber grating is maintained in a relatively straight orientation without buckling when compression strain is applied to the fiber. An actuator may be employed to control the strain applied to the fiber, i.e., to axially compress or stretch the fiber grating by driving one or both of the slides in a controlled manner. The resonance wavelength of the fiber grating can be tuned as a function of the strain applied to the fiber. The confinement member may alternatively include deformable slides which axially deform, i.e., extend and retract so as to change in length. Each end of the fiber is affixed to both of the deformable slides so that axial compression or stretching of the fiber grating is achieved through deformation of the deformable slides. The fiber grating tuning device can be deployed in components such as tunable fiber lasers and tunable fiber filters.
