摘要： The invention reduces the effects of stitching errors from re-scaling or re-positioning in the fabrication of fiber Bragg gratings or the mask used in such fabrication. A first embodiment of the invention preferably uses characteristics of stitching errors to compensate for the stitching errors themselves. By increasing the number of stitching errors, errors caused by the stitching errors can be reduced. A second embodiment uses continuous writing of the desired pattern, wherein the desired pattern is snapped to a grid that can be written by the fabrication equipment. Using continuous writing eliminates stitching errors in the resulting gratings.

摘要： Techniques for designing efficient gratings with multiple frequency response channels based on sampled patterns based predominantly on phase modulation of the underlying grating structure. Each period of the phase sampled patterns may include contiguous, discrete phase segments with different phase values, or alternatively, a continuous spatial phase pattern that changes the phase of the underlying grating structure. Moderate amplitude modulation of the underlying grating structure by the sampling structure may also be used together with phase modulation. The grating period or the sampling period may be chirped.

摘要： A phase mask, for writing fiber Bragg gratings (FBG) in an optical fiber, adjusts the amplitude and the phase of the FBG, while maintaining a constant mean index of refraction of the fiber in a single pass. Specifically, the phase mask embodies the amplitude information so that the amplitude information is an integral part of the phase mask and preferably cannot be separated from the phase information. A first embodiment employs a reflective or opaque surface, defining a window, on the substrate of a phase mask controlling the amplitude of light passing through the phase mask. Another embodiment employs a polygonal shaped grating region on a clear substrate. A third embodiment interleaves regions of grating and smooth substrate surface. Preferred embodiments employ two areas of gratings with the areas disposed: perpendicularly, out of bandwidth or out of phase, relative to each other or additive.

摘要： An X-cube integrated solid-optics component which can perform beam-splitting and filtering functions among four input beams. The X-cube component can also be used for various wavelength-division multiplexing communication and interconnection applications, such as star-coupling, wavelength routing, and add/drop multiplexing. The X-cube component comprises an assembly of four right-angle roof-top prisms positioned with the apex of each roof-top prism at the center of the assembly, such that assembly defines two mutually orthogonal and intersecting internal planes which intersect at the center of assembly to form four sections of the intersecting internal planes. The four plane sections form up to four or more primary optical channel paths having up to four or more potential inputs IAI, IBI, ICI, IDI and four or more potential outputs IAO, IBO, ICO, and IDO, and the outputs depend upon functionalities provided by the four sections of the intersecting internal planes.
