1 results about "Waveguide sensor" patented technology

An optical waveguide sensor includes: a core that extends in a given direction and that guides examination light; a cladding that has a refractive index lower than the core and that surrounds at least part of a circumference of the core; and a groove that is positioned on a side of the core in a first direction such that an oozing component of the examination light that is guided by the core leaks, an end face of the groove being positioned on a side of a second direction orthogonal to the first direction with respect to an end of the core.
