Abstract
Abstract A coaxial optoelectronic mount is provided. A coax cable having an inner conductor, an outer conductor, and an insulating region therebetween, and an end is formed. The end of the coax cable exposes portions of the inner conductor, the outer conductor, and the insulating region. A photonic device having a working portion, a first contact, and a second contact is mounted on the end of the coaxial cable. An optical fiber having a core region with a refractive index, a cladding region with a refractive index, and a surface is aligned to the working portion of the photonic device. An optical gel having a refractive index is disposed on the surface of the optical fiber and on the working portion of the photonic device operatively coupling the core region of the optical fiber to the working portion of the photonic device.
