Patent ID: 7061949

Claim:
A packaged semiconductor laser transmitter for high modulation bandwidth, the packaged semiconductor laser transmitter comprising: a thin-outline device package including a header with a first pin and a second pin feeding through the header and a third pin coupled to a bottom of the header, the first pin being closer to a center of the header than the third pin, the first pin having a first feedthrough impedance and the second pin having a second feedthrough impedance; a first feedthrough between the first pin and the header; a second feedthrough between the second pin and the header; a photodetector and a submount mounted within the thin-outline device package, a bottom surface of the photodetector and a bottom surface of the submount coupled to the header, the photodetector having an electrical contact on a top surface with a first input impedance; a semiconductor laser mounted within the thin-outline device package, a bottom surface of the semiconductor laser coupled to a top surface of the submount, the semiconductor laser having an electrical contact on a top surface with a second input impedance; a first bondwire with a first length coupled between a post of the first pin and the electrical contact of the semiconductor laser; a second bondwire with a second length coupled between a post of the second pin and the electrical contact of the photodetector; and wherein the first pin being closer to the center of the header than the third pin to minimize the first length and an inductance of the first bondwire.
