Problems solved by technology

However, when a metal wire is used to connect the semiconductor laser chip to the transmission line, the characteristic impedance mismatch is likely to occur due to the influence of the inductance component of the metal wire.
When a characteristic impedance mismatch occurs, reflection and / or transmission loss of the signal at the characteristic impedance mismatch point occurs, and the transmission characteristic may decrease

Description

technical field [0001] The invention relates to an optical modulator carrier assembly and an optical module. Background technique [0002] Patent Document 1 discloses an optical module including a laser diode that inputs a high-frequency signal and outputs an optical signal. In this optical module, the first transmission line and the second transmission line extend in parallel to each other on different pairs of planes. The laser diode is arranged between a pair of planes where the first transmission line and the second transmission line extend. One electrode of the laser diode is electrically connected to the first transmission line through a metal block interposed between the one electrode and the first transmission line. The other electrode of the laser diode is placed on the second transmission line and electrically connected to the second transmission line. [0003] Patent Document 2 discloses a laser module in which a semiconductor integrated light source in which a...
