  • Patent number: 6157765
    Abstract: An improved waveguide optical amplifier having an optically transparent first cladding layer, an optically transparent film doped with an optically active material, disposed over the first cladding layer, at least one undoped optically transparent film disposed over the doped film and coating etched walls of the doped film, and an optically transparent second cladding layer disposed over the undoped film. At least a portion of the undoped film disposed immediately adjacent the doped film has an index of refraction which is closer to the index of refraction of the doped film, than to the index of refraction of the second cladding layer and preferably equal thereto. The undoped film covers surface imperfections in the etched walls of the doped film, effectively moving them from the doped film/undoped film interface to the undoped film/cladding layer interface thereby reducing scattering of the high-intensity mode field.

  • Patent number: 6154590
    Abstract: In accordance with the invention, a tunable optical grating device comprises a grating, which is fixed at both ends to a support frame and is flexed so that a tensile strain induced in the grating reconfigures the resonant wavelength. Typical embodiments include mechanical or magnetic latching arrangements capable of inducing a latchable change in grating periodicity. In typical embodiments programmable and latchable magnets accurately produce a predetermined amount of fiber deflection and tensile strain, thereby producing a latchable wavelength shift with minimal power. The device is especially useful in WDM communication systems for adding or dropping channels, for dynamically gain-equalizing optical amplifiers, for tuning lasers, and for dispersion compensation.

  • Patent number: 6146913
    Abstract: This invention is predicated on applicant's discovery that near the gate dielectric/semiconductor interface, surface roughness of a particular spectral range plays a disproportionately larger role in scattering electrons and impeding their transport. Moving electrons will not enter the nooks and crannies of roughness having wavelength shorter than about 100 .ANG. and therefore are not affected by them, and electrons are less affected by roughness having wavelengths longer than about 1000 .ANG.. Accordingly, it is desirable to reduce the surface roughness of gate dielectrics at the interface. This can be accomplished prior to dielectric formation by inspection of semiconductor wafers for surface roughness and rejection of those wafers with high surface roughness content in the range 100 .ANG. to 1000 .ANG.. Such inspection also provides a valuable criterion for selecting optimum semiconductor processing steps.

  • Patent number: 6148128
    Abstract: In accordance with the invention, a passively temperature-compensated tunable optical grating device comprises a grating, which is fixed at both ends to a support frame, and is mechanically or magnetically flexed so that a tensile strain induced in the grating reconfigures the resonant wavelength of the grating. Preferred embodiments include at least one waveguide grating, a flexing mechanism capable of inducing a latchable change in grating periodicity and at least one negative thermal expansion component which, upon heating, reduces the strain in the grating so that the temperature-induced wavelength shift is substantially cancelled out. The device can reduce the temperature-dependent wavelength change to less than 0.5 nm/100 deg. C, and preferably less than 0.05 nm/100 deg. C. In a preferred embodiment, the packaging assembly also includes a fine-wavelength adjusting mechanism for post-assembly corrective tuning.

  • Patent number: 6142959
    Abstract: The present invention relates to a method for mechanically imaging the prostate with a prostate examination device. In the method, position data and pressure response data are acquired along predetermined trajectories overlaying the prostate by periodic pressing or sliding of a pressure sensor assembly attached to a probe against the prostate. In a preferred embodiment, the prostate examination device comprises a probe sized to fit within the rectum and having a head connected by a shaft to a handle. A support is connected to the probe for providing a point of rest for the shaft during the prostate examination. As the pressure sensor assembly is pressed against and moved over the prostate, it generates signals in response to forces imposed on the pressure sensor assembly. A positioning system is coupled to the support and probe for determining position data of the pressure sensor assembly during prostate examination.

  • Patent number: 6136667
    Abstract: A process for device fabrication is disclosed in which two substrates having different crystal lattices are bound together. In the process the substrate surfaces are thoroughly cleaned and placed in physical contact with each other. The duration of the contact and the pressure of the contact are selected to facilitate a bond between the two substrate surfaces that results from attractive Van der Waals' forces between the two surfaces. The bonded substrates are heated to a moderate temperature to effect escape of gases which may be entrapped by the substrates. The bulk of one of the substrates is then typically removed. The substrates can be heated again to a moderate temperature to effect removal of any gases remaining entrapped on the substrates. Thereafter, the bonded surfaces are heated to a high temperature to effect a permanent bond.

  • Patent number: 6132827
    Abstract: A multilayer industrial stretch film is provided with at least one cling layer and is formed by coextruding a film-formable polymer with a tackifier. The invention provides a multilayer film having at least two skin layers and at least one core layer in which at least one of the skin layers is derived from a mixture of the tackifier and the film-formable polymer. At least one of the core layers can include a vapor corrosion inhibitor (VCI). Beneficial results are obtained by also including a lubricating composition in at least one, if not both, skin layers when at least one of the core layers contains a VCI. The lubricant in the skin layer effectively reduces the extrusion temperature (for blown and cast films), and tends to avoid degrading or igniting the VCI.
