Claim Text:
1. An integrated optoelectronic device, comprising: a body of semiconductor material having formed inside at least a first optoelectronic component that is one of a detector and an emitter; an optical path integrally formed in the body of semiconductor material and traversing the body and extending between a first surface and a second surface; wherein the first optoelectronic component is optically coupled through the optical path to a first transmission medium and a second transmission medium arranged, respectively, above and underneath the first and second surfaces; and wherein the integrated optoelectronic device further comprises a top region, arranged on top of the body and forming the first surface, the body being delimited by the second surface and by a main surface, the main surface being arranged between the first and second surfaces; and wherein the optical path is formed by a first confinement region and a second confinement region, the first confinement region extending within the top region, starting from the first surface, the second confinement region extending within the body, starting from the second surface; and wherein the first confinement region is surrounded laterally by a first lateral region, which has a refractive index less than the refractive index of the first confinement region so that the first confinement region and the first lateral region form a first coupling waveguide; and wherein the second confinement region is surrounded laterally by a second lateral region, which has a refractive index less than the refractive index of the second confinement region so that the second confinement region and the second lateral region form a second coupling waveguide.
