Abstract:
Provided are an optical waveguide capable of propagating light, and a position sensor and an optical circuit board including the same. The optical waveguide includes cores each partially formed in an S-shape. The S-shaped portion includes a first curved portion upstream as seen in the direction of light propagation, and a second curved portion downstream as seen in the direction of light propagation and curved in a direction opposite to the first curved portion. The first curved portion and the second curved portion are connected to each other via a straight portion having a length in the range of greater than 0 mm to 30 mm. One of the width of the exit of the first curved portion and the width of the entrance of the second curved portion is smaller than the width of a core portion upstream of the S-shaped portion.

Claim (Index 1):
An optical waveguide comprising:\n a linear core serving as an optical path; and upper and lower cladding layers holding the core therebetween, wherein the core is partially formed in an S-shape, wherein the S-shaped portion includes a first curved portion upstream as seen in the direction of light propagation, and a second curved portion downstream as seen in the direction of light propagation and curved in a direction opposite to the first curved portion, wherein the first curved portion and the second curved portion are connected to each other via a straight portion having a length in a range of greater than 0 mm to 30 mm, and wherein one of the width of the exit of the first curved portion and the width of the entrance of the second curved portion is smaller than the width of a core portion upstream of the S-shaped portion.
