摘要： The present invention provides a method for annealing an optical waveguide, including an optical fiber or large-diameter waveguide structure, having along some length an induced refractive index difference that decays over time and so causes drift in the wavelength of reflected light when broadband light is inserted into the optical waveguide. The method uses an assumed decay formula for the induced refractive index difference indicating how the induced refractive index difference decays over time, the assumed decay formula having parameters that depend on temperature. The method includes the steps of: determining the (temperature dependent) parameters in the assumed decay formula for both an operating temperature and an annealing temperature, the annealing temperature being higher than the operating temperature, by fitting the observed decay over a measuring time at the two temperatures; and determining an anneal time at the annealing temperature based on a maximum allowed drift at the operating temperature. In operation, an optical waveguide is then annealed at the anneal temperature for the anneal time to provide a heat treatment (annealing) process for stabilizing Bragg gratings inscribed in the optical waveguide.

摘要： A tunable optical filter has a large diameter cane waveguide with “side-holes” in the cane cross-section that reduce the force required to compress the large diameter optical waveguide without overly compromising the buckling strength thereof. The large diameter optical waveguide has a cross-section of at least about 0.3 millimeters, including at least one inner core, a Bragg grating arranged therein, a cladding surrounding the inner core, and a structural configuration for providing a reduced bulk modulus of compressibility and maintaining the anti-buckling strength of the large diameter optical waveguide. The structural configuration reduces the cross-sectional area of the large diameter optical waveguide. These side holes reduce the amount of glass that needs to be compressed, but retains the large diameter.

摘要： A compression-tuned fiber Bragg grating based reconfigurable wavelength add/drop module has a compression force assembly and an all-glass Bragg grating compression unit having gratings spaced along an axis of compression. The compression force assembly responds to a control electronics signal containing information about a selected wavelength of a channel to be added to or dropped from an optical traffic signal, for providing a compression force applied along the axis of compression. The compression unit responds to the optical traffic signal and the compression force, for providing an all-glass Bragg grating compression unit optical signal having the selected wavelength of the channel to be added to or dropped from the optical traffic signal. The compression unit optical signal may include either the traffic with an added reflected channel(s), or a dropped reflected channel(s). The compression unit is a “dogbone” structure having either a glass tube with an optical fiber fused therein, or a single large diameter waveguide having a core. The core of the optical fiber or waveguide has the gratings spaced therein. The axis of compression is parallel with the longitudinal axis of the dogbone structure.

摘要： The present invention provides a new and unique method for increasing the photosensitivity of a large diameter optical waveguide having a cross-section of at least about 0.3 millimeters. The method features loading the large diameter optical waveguide with a photosensitizing gas at a pressure at least about 4000 pounds per square inch (PSI) at a temperature of at least about 250E Celsius.

The method may be used as part of a process for writing a Bragg grating in an inner core or a cladding of the large diameter optical waveguide.
