<p>An optical module provided with an optical guide having a totally novel lens function. An optical module comprising an optical guide that has a core part through which light is propagated along the z-axis of a coordinate system in which the z-axis is the optical axis along which the light is propagated, the x-axis is the vertical axis in the cross section perpendicular to the z-axis, and the y-axis is the horizontal axis in the cross section and a clad layer covering the core part. The core part is composed of cores, and the y-z cross section of at least one of the cores has a generally circular shape, a generally elliptic shape, or a shape similar to those.</p> |
