Abstract
A transistor outline (TO) housing comprising a base part having a mounting area for a thermoelectric cooler, wherein the base part has at least two feedthroughs for connecting an optoelectronic component. A support extends from the upper surface of the base part, which support has at least two conductor traces arranged thereon, each of which is connected to a respective one of the feedthroughs for connecting the optoelectronic component.
Claims19
A transistor outline housing for connecting to an optoelectronic component, comprising:
- a base part having an upper surface, the upper surface having a cooler mounting area;
- two feedthroughs configured to be connected to the optoelectronic component;
- a support that extends from the upper surface of the base part, wherein the support has two conductor traces arranged thereon, each of the two conductor traces being connected to a respective one of the two feedthroughs;
- and
- a ground conductor trace arranged on the support between the two conductor traces
- a trace sub-mount on a front side of the support, a thermoelectric cooler, the optoelectronic component, and a component sub-mount,
- wherein the thermoelectric cooler is arranged on the cooler mounting area of the base part, the component sub-mount extending above at least portions of the thermoelectric cooler and extending perpendicular to the upper surface of the base part, and
- wherein the component sub-mount adjoins the trace sub-mount.
