  • Contact probe and socket for testing electrical component
    Patent number: 11841380
    Abstract: The embodiments of the present disclosure provide a contact probe and a socket for testing an electrical component. The contact probe includes: a tubular structure in which a receiving cavity is formed, and a contact part for contacting with a terminal of a first electrical component is provided at a first end of the tubular structure; a spring arranged in the receiving cavity; a plunger connected with the tubular structure in a slidable manner, wherein a first end of the plunger is provided with a spring positioning part, which abuts against the spring and is an eccentric structure arranged offset from a central axis of the plunger, a second end of the plunger projects from a second end of the tubular structure.
    Type: Grant

  • Optical switch
    Patent number: 7200290
    Abstract: An optical switch has an optical waveguide whose output path of an optical signal branches into two, a carrier injection section which is provided to a branch portion of the optical waveguide and to which carriers are injected, and a refractive index change section which is provided to a optical waveguide layer of the optical waveguide and in which a refractive index changes in a case that carrier are injected to the carrier injection section, wherein the refractive index change section has a quantum dot or a quantum wire.
