Abstract

An input impedance matching circuit unit is employed, which is connected between a laser diode chip and a modulation signal input terminal in a module package of a semiconductor laser module that directly modulates micro-wave frequency signals. This input impedance matching circuit unit integrates structural elements such as a micro-strip line, a reactance element, and a bonding wire on a single dielectric surface.
