Abstract

See full text

An optical probe includes a first region and a second region connected to have a continuous optical waveguide in which a transmission mode is a single mode. The first region connected to a tip-end surface opposed to an optical device includes a region in which a mode field diameter that is maximum at the tip-end surface is gradually decreased toward a boundary between the first region and the second region. The tip-end surface is a curved surface and has a radius of curvature set so that an advancing direction of an optical signal entering through the tip-end surface approximates in parallel to a central-axis direction of the optical waveguide.
