Abstract
There are provided an optical waveguide including cores arranged in a lattice form in which intersection loss is further reduced where, at each intersection of the cores including first and second cores extending in two intersecting directions, the first core is separated by the second core and a gap is formed between the second core and each of the end portions of the first core, and a position sensor using the same. The position sensor includes an optical waveguide including cores arranged in a lattice form. At each intersection of the cores including first and second cores extending in two intersecting directions, the first core is separated by the second core, and a gap is formed between the second core and each of the end portions of the first core. The width of the end portions of the first core is greater than the width of the second core.
