    Abstract: Use of ultrashort, focused pulses to alter a detectable optical property in a specific region in a structure allows lower energy to be used in fabrication of a three-dimensional, periodic array of altered regions in a material. These properties may be, for example, an index of refraction, absorption or scattering. The typical spacing between altered regions may be larger than a wavelength of interest, to create diffractive optical elements, or may be roughly the same as a wavelength of interest, to create photonic crystal elements. The photonic crystal may have a photonic band gap, i.e., a frequency range in which no modes may propagate, or may simply have altered dispersion properties but no gap, as in a photonic crystal superprism.

    Abstract: Methods of drawing glass sheet via a downdraw process are provided. In certain aspects, the methods utilize rapid cooling below the root (70) of the forming apparatus (10). Such rapid cooling can, for example, facilitate the use of glass having a liquidus viscosity less than about 100,000 poise. In other aspects, the methods utilize slow cooling between the viscosities of 10 11 poises and 10 14 poises. Such slow cooling can facilitate the production of glass substrates which exhibit low levels of compaction. In further aspects, substrates are removed from the glass sheet at elevated temperatures which can facilitate increases in the production rates of downdraw machines. In still further aspects, rapid cooling below the root, slow cooling between the viscosities of 10 11 poises and 10 14 poises, and/or substrate removal at elevated temperatures are combined. Such combinations can facilitate economically effective utilization of downdraw equipment.

    Abstract translation: 提供了通过下拉工艺绘制玻璃板的方法。 在某些方面，该方法利用在成形装置（10）的根部（70）下方的快速冷却。 这种快速冷却可以例如有利于使用液相线粘度小于约100,000泊的玻璃。 在其它方面，该方法利用在10psi和10psi之间的粘度之间的缓慢冷却。 这种缓慢的冷却可以促进显示低压实水平的玻璃基板的生产。 在另外的方面，在升高的温度下将基材从玻璃板上除去，这可以促进下拉机的生产速率的增加。 在另外的方面，将根部下方的快速冷却，在10psi的粘度和10-14个泊位之间的缓慢冷却和/或在升高的温度下的基底去除被组合。 这种组合可以有助于经济上有效地利用下拉设备。

    Abstract: A magnetic photonic crystal for providing asymmetry of spatial frequencies in the propagation of light is provided. The crystal is formed from at least two materials having different indices of refraction which are aligned along the longitudinal axis of the crystal. And arranged in an array whose symmetry does not include a spatial inversion operator such that (x,y) =/= (-x,-y). One or more of the materials forming the array is magnetic such that the magnetic group representation of the array does not include time inversion as a symmetric operator. In operation, when the magnetic material forming the material is magnetized, the group velocity property of light propagated in one direction along the axis of the array is different from the group velocity property of light transmitted in an opposite direction through the array. The magnetic photonic crystal may be used, for example, as an optical memory device or a high speed modulator/demodulator.

    Abstract: A method of determining parameters of plurality of thermal cycles to achieve a set glass strain level includes providing a plurality of input parameters for a glass substrate and a plurality of parameters for a plurality of thermal cycles. The method also includes iteratively modifying at least one of the pluralities of thermal cycle parameters so the glass strain is not greater than the set glass strain level after a final thermal cycle is completed. An aspect of the method usefully enables a user to determine from the material parameters and processing sequences of the glass manufacturer and further entities that may further process the glass (e.g., the glass manufacturer's customers) whether a particular glass strain can be achieved; and if not the example embodiments allows the manufacturer to calculate changes in the customers' processes to meet the desired glass strain.

    Abstract: Disclosed is a photonic band-gap crystal waveguide having the physical dimension of the photonic crystal lattice and the size of the defect (12, 20) selected to provide for optimum mode power confinement to the defect. The defect (12, 20) has a boundary which has a characteristic numerical value associated with it. The ratio of this numerical value to the pitch (4) of the photonic crystal is selected to avoid surface modes found to exist in certain configurations of the photonic band-gap crystal waveguide. Embodiments in accord with the invention having circular and hexagonal defect cross sections are disclosed and described. A method of making the photonic band-gap crystal waveguide is also disclosed and described.
