1. A header for optoelectronic applications, comprising:
a header base extending in a height direction, a width direction, and a longitudinal direction, the header base having a base back face, a base front face, and at least two openings that extend from the base back face through the header base along the width direction to the base front face;
a pin fixed in each of the openings so that the pin is electrically isolated from the header base;
a first pedestal and a second pedestal arranged at the base front face, the first and the second pedestal being arranged mirror symmetrically with respect to an imaginary plane parallel to the height direction and the width direction, the first pedestal and the second pedestal being below, in the height direction, a center of one of the openings, the first pedestal and the second pedestal each comprising a pedestal mounting face, a pedestal free face that is opposite the pedestal mounting face, and an upper surface, the upper surface being sized and configured for mounting and carrying a pedestal submount, wherein the pedestal upper surface faces the respective pin,
wherein the pedestal mounting faces are fixedly attached to the base front face with an electrically conductive material that is at least partially arranged between the base front face and the pedestal mounting faces,
wherein each pedestal comprises a bar arranged on the upper surface thereof and directed perpendicular to the longitudinal and height direction and the bar extending along one of the side faces of the pedestal to form a sidewall adjacent to the upper surface, wherein a L-shape of each of the first and second pedestal is formed by the first bar and the upper surface of the pedestal.
