    Abstract: An improved method and apparatus for mode-locking a fiber laser at a pre-selected frequency wherein a doped fiber segment contains a narrowband FBG and an electro-optically tuned FBG, thereby making obsolete the need for an EOM to modulate the laser's wavelength. The present invention also provides a method and apparatus for mode-locking a fiber laser at a variable frequencies wherein a doped fiber segment contains two electro-optically tuned FBG's. The electro-optically tuned FBG may be fabricated by a thermal poling process.

    Abstract: Methods and systems that provide for cross-linking from composite images that include receiving, over a computer network, a source image and then associating a first identifier tag with a first object in the source image. A composite image is generated from the source image, wherein the composite image includes a cropped image of the first object. Then a first user is notified that the first identifier tag is associated with the first object in the cropped image and also includes a copy of the composite image. Additionally, the user can select the first object in the composite image and be linked to the source image that contains the selected first object where the first object is highlighted.

    Abstract: A fiber Bragg grating cross-wire sensor may be used to independently determine strain and temperature variation. An example fiber Bragg grating cross-wire sensor comprises a first fiber Bragg grating (FBG) that reflects a first percentage, R1, of light of a first wavelength, λ1, and a second FBG that reflects a second percentage, R2, of light of a second wavelength, λ2. The second FBG is positioned orthogonal to the first FBG, and λ1 is substantially equal to λ2, but R1 is different from R2. As the FBG cross-wire sensor experiences a strain and/or a temperature variation, the wavelengths of light reflected by the first FBG and the second FBG will shift from the first and second wavelength, λ1 and λ2, to first and second shifted wavelengths, λA and λT, respectively. Based on R1, R2, λ1, λA, and λT, the strain and/or the temperature variation may be independently determined.
