Abstract
A novel optoelectronics package includes an optical semiconductor, an electronic cooling element carrying the optical semiconductor and electrically connected to one of the terminals thereof, a pair of transmission lines having distributed constant characteristics and an airtight vessel housing the optical semiconductor, cooling element and transmission lines. A grounding line of the transmission lines is connected between the terminal of the optical semiconductor and an external ground terminal fixed at the vessel. A signal line of the transmission line is connected between the other terminal of the optical semiconductor and an external signal terminal, whereby the stray capacitance of the cooling element is shorted by the distributed constant grounding line.
