  • Patent number: 11970390
    Abstract: The present disclosure provides a method for producing a microchannel device, which can form a channel that has high hydrophobicity, high solvent resistance as well, and also resistance to heat and damage, on demand with high accuracy, and produces the microchannel device at a low cost, while having high productivity. The method for producing a microchannel device includes: forming a channel pattern from a hydrophobic resin on a porous substrate by an electrophotographic method; melting the channel pattern by heat to allow the channel pattern to permeate into the porous substrate, thereby forming a channel in the inside of the porous substrate.

  • Publication number: 20220082769
    Abstract: To relax the accuracy with respect to a positional deviation, and thus to reduce costs. An optical waveguide and a light path adjuster are included, the optical waveguide performing propagation only in a reference mode at a first wavelength, the light path adjuster adjusting a light path such that input light is guided to a core of the optical waveguide. Communication is performed using light of a second wavelength that enables the optical waveguide to perform propagation in at least a first order mode in addition to the reference mode. When there is a positional deviation, input light that is not headed for the core of the optical waveguide is guided to the core due to the light path adjuster adjusting a path of the light. This results in a reduction in a loss of coupling of optical power.
