Inventor: SAITO TSUNEAKI
IPC: G02B6/12
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a small and low cross talk optical module for wavelength multiplexing and demultiplexing. SOLUTION: Array waveguide type gratings 9 (9a to 9d) for bandpass are respectively connected to five optical output waveguides 26 of an array waveguide type grating 20 for multiplexing and demultiplexing which functions as an optical wavelength multiplexing and demultiplexing device. Each array waveguide type grating 9 for the band passes pairs one light input port and one optical output port. The grating 9 transmits light with wavelengths centered on different light transmission central wavelengths with each other by respective input/output port pairs. Therefore, light with a plurality of wavelengths is transmitted and the optical background cross talk of each wavelength is reduced in a lump.  For example, light with light transmission central wavelengths λ1, λ2, λ3, λ4, and λ5 outputted from the array waveguide type grating 20 for multiplexing and demultiplexing is made incident on light input ports 2a, 2b, 2c, 2d, and 2e of array waveguide type grating 9a for bandpass, and is outputted from optical output ports 6b, 6e, 6c, 6a, and 6d.

IPC: B24B37/20
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a polishing device capable of reducing the inclination of a polishing pad when an overhang occurs. SOLUTION: The air is fed in a hollow part 15 from an air feed port 14 formed in a rotation shaft 1, and the air is fed to bag bodies 13A-13F through air vents A-F.

When the polishing pad 19 is pressed against the surface of a wafer 12 in polishing, each bag body is used as a cushioning material to facilitate the polishing pad 19 to follow the surface of the wafer 12. When the overhang occurs, the right side of the base plate 7 is lowered and the left side thereof is about to go up. Since circulation of the air among the respective bag bodies is executed only through the small air vents A-F, only a small amount of the air is moved among the respective bag bodies in a short time. Each bag body is deformed a little from its original position, and its deformation amount is not large.
