摘要： A method for producing a protected optical fiber with distributed sensors includes heating an optical fiber preform and drawing the heated optical fiber preform to form a drawn optical fiber. The method also includes coating the drawn optical fiber with a carbon coating after the optical fiber is drawn to provide a carbon coated optical fiber and then writing a series of fiber Bragg gratings (FBGs) into the carbon coated optical fiber to provide a carbon coated optical fiber with FBGs. The method further includes coating the carbon coated optical fiber with FBGs with one or more layers of a polymer to provide the protected optical fiber with distributed sensors, wherein the heating, drawing, carbon coating the drawn optical fiber, writing, coating the carbon coated optical fiber are performed in that sequence while the protected optical fiber is being produced.

摘要： Devices and methods for optical-fiber processing for connector applications are disclosed, wherein the devices and methods utilize a quantum cascade laser operated under select processing parameters to carry out end face polishing. The method includes supporting the optical fiber in a ferrule so that a bare end section of the fiber protrudes from an end of the ferrule by a protrusion distance. The method then includes irradiating the end face with light from the quantum cascade laser to polish the end face. The quantum cascade laser can also be used to form a bump in a central portion of the end face, wherein the bump facilitates physical contact between respective end faces of connected optical fibers.

摘要： A superstructure fiber Bragg gratings (FBG) by laser-assisted direct writing of on-fiber metallic films. A laser direct write method is used to fabricate periodic films of silver nanoparticles on the non-planar surface of as-fabricated FBGs. Silver films with a thickness of about 9 μm are fabricated around a Bragg grating optical fiber. The performance of the superstructure FBG is studied by applying temperature and tensile stress on the fiber. An opto-mechanical model is also developed to predict the optical response of the synthesized superstructure FBG under thermal and structural loadings. The reflectivity of sidebands in the reflection spectrum can be tuned up to 20% and 37% under thermal and structural loadings, respectively. In addition, the developed superstructure FBG is used for simultaneous measurement of multiple criteria such as force and temperature to eliminate the inherent limitation of regular FBGs in multi-parameter sensing.

摘要： The present invention is directed to the creation of optical waveguiding devices from standard optical fibers by the creation of zones of permanently altered refractive index characteristics therein. A high intensity femtosecond laser beam is focused at a predetermined target region in the fiber so as to soften the glass material at the target region. After aligning the focal region with the target region in the fiber there will be relative movement between the focal region and the fiber, which has the effect of sweeping the focal region across the fiber in a predetermined path, so as to create a secondary waveguide path. A portion of the light traveling along the core is removed from the core along the secondary waveguide path such that the device can be utilized as an attenuator, an optical tap, or a polarimeter.
