An optical device includes at least one optical waveguide including a plurality of elongate portions. Light propagates sequentially and generally along the elongate portions.
The instability of the mean wavelength of a superfluorescent fiber source (SFS) is reduced by randomizing the polarization of light from a pump source or by using polarization maintaining components.
In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide made from a rare-earth-doped amorphous yttrium aluminum oxide material (e.g., erbium-doped yttrium aluminum oxide material).

An optical sensor includes at least one optical coupler and an optical waveguide in optical communication with the at least one optical coupler. The optical waveguide is configured to receive a first optical signal from the at least one optical coupler.
An acoustic sensor and a method of fabricating an acoustic sensor are provided. The acoustic sensor includes at least one photonic crystal structure and an optical fiber having an end optically coupled to the at least one photonic crystal structure.
This optical gyroscope uses a unidirectional coupled-resonator waveguide to enhance the Sagnac effect. Thus, this device offers greater sensitivity to rotation than conventional resonant or interferometric fiber-optic gyroscopes.
A method estimates a nonlinearity profile of a material. The method includes providing a magnitude of a transform of a measured nonlinearity profile measured from the material.
An optical fiber includes a cladding with a material having a first refractive index and a pattern of regions formed therein. Each of the regions has a second refractive index lower than the first refractive index.
A method and apparatus models one or more electromagnetic field modes of a waveguide. The method includes sampling a two-dimensional cross-section of the waveguide.
To determine the phase and magnitude of the complex electric field of
weak ultra-short pulses we propose to use a dummy strong pulse time
delayed relative to the weak pulse that needs to be characterized. This
