Abstract: <P>PROBLEM TO BE SOLVED: To reduce wavelength dispersion of an arrayed waveguide diffraction grating optical multiplexing and demultiplexing circuit such that an input optical waveguide coupled with an input-side slab waveguide of an AWG is in a parabolic shape.  <P>SOLUTION: The arrayed waveguide diffraction grating optical multiplexing and demultiplexing circuit has a structure constituted by connecting a wide waveguide (multi-waveguide) 201 between a slab waveguide and a parabolic waveguide 106. The width D2 of the multi-waveguide 201 is equal to the width D1 of the parabolic waveguide 106 (D<SB>2</SB>=D<SB>1</SB>) or a little narrower than that of the parabolic waveguide (D<SB>2</SB><D<SB>1</SB>). The width of the multi-waveguide is numerically limited by that the maximum width is less than or equal to that of the parabolic waveguide and the minimum width satisfies (the value of the standardized frequency (v) is larger than π). The effect that wavelength dispersion becomes zero is obtained by setting the length of the multi-waveguide to an optimum value (the length where the phase difference between a mode of 0th order and a mode of 2nd order at an end becomes zero).  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To enable easy recognition of corresponding relations between a 3 D probe (or three-dimensional space) and a cut surface, when forming the three-dimensional space by the 3 D probe and displaying a tomographic image equivalent to the cut surface which is set in the three-dimensional space.  <P>SOLUTION: The 3 D probe 10 is provided with a first physical mark 18 corresponding to a theta direction, and a second physical mark 20 corresponding to a phi direction. When displaying the cut surface set in the three-dimensional space V as the tomographic image, a first indication mark is displayed corresponding to the first physical mark 18 and a second indication mark is displayed corresponding to the second physical mark 20. Through the indication marks, a position and a direction of the cut surface are intuitively recognized in an observation of the tomographic image. The first physical mark corresponds to a base point in the theta direction or corresponds to a cut surface direction including the theta direction. The second physical mark corresponds to a base point in the phi direction, or corresponds to a cut surface direction including the phi direction.  <P>COPYRIGHT: (C)2004,JPO
