Abstract: Described are optical fibers, e.g., for use in stress-sensing or shape-sensing applications, that use overlapping grating configurations with chirped gratings to facilitate strain delay registration. In accordance with various embodiments, a fiber core may, for instance, have two overlapping sets of chirped gratings that differ in the direction of the chirp between the first and second sets, or a set of chirped gratings overlapping with a single-frequency grating. Also described are strain sensing systems and associated computational methods employing optical fibers with overlapping gratings.

Abstract: When a grating is inscribed in a section of optical fiber through a coating of the optical fiber, using a light modulation mask to modulate the light beam that writes the grating, a fluid can be situated between the section of optical fiber and the back side of a mask component carrying the light modulation mask (e.g., on its front side) to reduce the refractive-index discontinuity encountered at the surface of the coating. In various embodiments, rather than running the fiber through a vessel containing the fluid, the fluid is run across the back side of the mask component or retained by capillary action between the fiber section and the mask component.

Abstract: In a tunable transmission-grating laser, alignment of the lasing cavity mode with the grating filter spectrum of the laser can be achieved using the position of the intracavity beam relative to the gain medium as feedback. In various embodiments, the displacements of the intracavity beam from the gain medium are monitored indirectly, using an image of the intracavity beam created outside the cavity with an additional transmission grating. Various means for measuring the position of that monitoring beam and for adjusting the tunable components of the laser based thereon are described.

Abstract: A system can direct light into an optical fiber. Imaging optics can form an image of an end of an optical fiber. An actuatable optical element can be configured to define an optical path that extends to the actuatable optical element and further extends to the end of the optical fiber. A processor can determine a location in the image of a specified feature in the image. The processor can cause, based on the location of the specified feature in the image, the actuatable optical element to actuate to align the optical path to a core of the optical fiber. A light source can direct a light beam along the optical path to couple into the core of the optical fiber.
