Title: Apparatus and method of measuring optical properties of diffractive optical element
Inventor: FUSE KEIJI
IPC: G02B5/18
Filed: 2003-01-10
Abstract: A laser beam emitted from a laser source is split by a beam-splitting means such as a beam sampler, and the power Q of the split beam is measured by a first detector. In addition, the power q1 of light that has passed through a pinhole while a DOE is not set is measured by a second detector, and the power ratio .alpha. = q1/Q is calculated. Then, the DOE is set and the power ratio .beta.k = q k/Q, where q k is the power of each light beam, is calculated. The power ratio .beta.k is evaluated on the basis of the power ratio .alpha., so the optical properties of a diffractive optical element, in particular, in terms of diffraction efficiency in laser-beam diffraction and intensity uniformity of split beams can be measured with high accuracy.

Abstract: The arrayed waveguide grating (AWG) is a known prior art optical multiplexer used in WDM optical communication systems. In the prior art flat-type AWG, the pulse waveform is distorted due to the dispersion in the AWG itself, and this forms a serious problem that makes it impossible to use the AWG as a multiplexer.      In order to solve the problem of the prior art, an optical multiplexer is equipped with at least one input channel optical waveguide provided on an optical waveguide substrate, a first slab optical waveguide, a channel optical waveguide array formed from a plurality of optical waveguides having a prescribed waveguide length, a second slab optical waveguide and at least one output channel optical waveguide sequentially connected in a tandem arrangement; and phase adjustment means for achieving the same phase distribution in the channel optical waveguide array.      In accordance with the optical multiplexer of the present invention, it is possible to reduce the dispersion of the AWG, and this makes it possible to construct a large-capacity WDM optical communication system.

Title: Chemical mechanical machining and surface finishing
Inventor: WINKELMANN LANE WILLIAM
IPC: B23F19/00
Filed: 2002-02-07
Abstract: The invention described herein discloses a chemical mechanical machining and surface finishing process. A conversion coating is formed on the surface of a workpiece and is removed via relative motion with a tool, thereby exposing the workpiece to further reaction with the active chemistry. Low mechanical forces are used such that the plastic deformation, shear strength, tensile strength and/or thermal degradation temperature of the workpiece are not exceeded. Since the chemical mechanical machining and surface finishing process requires little force and/or speed of contact to remove the conversion coating, the equipment's mass, complexity and cost can be significantly reduced, while simultaneously increasing machining precision and accuracy. The present invention lends itself to a very controlled rate of metal removal, and can simply surface finish the workpiece, or if desired, can surface finish the workpiece simultaneously with the shaping and/or sizing process.

Abstract: A base assembly used as a part of a mold assembly for forming a container has a base insert and a flow divider plate that co-operate to define a continuous fluid passageway for cooling or heating the base insert. The flow divider plate has an upper surface portion having at least one raised runway extending in a first pattern covering a substantial area of the upper surface portion. The base insert has a lower surface portion with a continuous channel extending in a second pattern. The channel is positioned adjacent the at least one raised runway in sealing relation therewith to define a continuous fluid passageway. The channel in the base insert is a recessed groove and a plurality of bores with dome shaped ends that extend from the lower surface portion of the base insert deeper into the base insert than the recessed groove. The raised runway has a plurality of baffles with rounded tips that extend outwardly therefrom and into a corresponding one of the bores to redirect flow of fluid through the bores. By utilizing a continuous fluid passageway in the base insert and the co-operating flow divider plate, any blockage in the passageway may be detected by the pumping system for the cooling fluid. Further, the passageway is readily formed by machining one face of the insert and one face of the flow divider plate and provides for enhanced heat transfer between the contoured surface of the base insert and coolant passing through the base insert.
