Abstract: A method and apparatus that includes a first waveguide segment that differentially changes the amplitude of the light relative to a first polarization orientation, a thickness of oriented liquid crystal or other birefringent material sufficient to delay one polarization component one-half wavelength relative to another, and a second waveguide segment that also differentially changes the amplitude of the light based on the polarization orientation. Also, an apparatus that includes a thin polarization converter that includes a thin first substrate that is substantially transparent to a wavelength of light, and a birefringent material deposited on one or more surfaces of the first substrate and oriented such that the polarization converter forms a half-wavelength birefringent plate for the light. Also, an apparatus having a first substrate surface, a second substrate surface, and a liquid crystal material between the first and second substrate surfaces to form a polarization converter.

Abstract: A semiconductor chip is shown containing an integral heat spreading layer that more effectively transmits heat from the die to ambient as a result of spreading the heat out on the die over a larger cross sectional area. Local hot spots are minimized which allows the semiconductor chip to operate at a higher frequency for a given upper threshold temperature. Also shown is a method of manufacturing such a semiconductor chip, and the associated method of cooling a semiconductor chip.

Abstract: To accommodate high power densities associated with high performance integrated circuits, heat is dissipated from a surface of a die through a solderable thermal interface to a lid or integrated heat spreader. In one embodiment, the die is mounted on an organic substrate using a C4 and land grid array arrangement. In order to maximize thermal dissipation from the die while minimizing warpage of the package when subjected to heat, due to the difference in thermal coefficients of expansion between the die and the organic substrate, a thermal interface is used that has a relatively low melting point in addition to a relatively high thermal conductivity. Methods of fabrication, as well as application of the package to an electronic assembly, an electronic system, and a data processing system, are also described.

Abstract: A flat-top arrayed waveguide grating with wideband transmission spectrum may be produced by integrating a series of directional couplers to the output slab waveguide coupler of a dual channel-spacing arrayed waveguide grating having Gaussian spectral profile. The primary channel spacing of the Gaussian arrayed waveguide grating determines the spectral width of the resultant wideband device, whereas the secondary channel spacing determines the wavelength separation between the adjacent output channels. In such a structure, a wideband or flat transmission spectral profile may be achieved without excessive losses.
