ABSTRACT:
A laser transmitter arrangement includes a plurality of laterally coupled semiconductor lasers along with drive components integrated on a single semiconductor body. The drive components include drop resistors, an inductance element, a capacitance element and are all applied to an insulating layer on the surface of the semiconductor body. The resistors are formed by interconnects, while the inductance element is a spiral interconnect and the capacitance element is formed by interconnects lying over one another with an intervening dielectric material. Electrical connection from contact surfaces of the semiconductor lasers to the drive components is provided by the interconnects. The semiconductor body also contains external contacting surfaces for a DC source and for a high frequency source.
