Optical wave-guide, light-beam spot converter and optical transmission module |
摘要 |
An optical transmission module includes at least one of a light emitting element and a light receiving element, an optical fiber and an optical wave-guide provided between the light emitting element or the light receiving element and the optical fiber. The optical wave-guide has a z-axis in a direction of light propagation, an x-axis in a vertical direction on a cross-sectional plane perpendicular to the z-axis, and a y-axis in horizontal direction thereon. The optical wave-guide includes a core portion formed so that light is transmitted in the direction of the z axis, around at a center of an origin of the x axis and y axis, and a crud layer which surrounds the core portion and is lower in refractive index than a refractive index of the core portion. The core portion includes a plural number of segments, and at least one of the segments has a recess portion.
