InP membrane disc lasers have been considered as light sources for off chip data communication for logic microprocessors or for all optical logic devices such as gates and flip-flops. However, another family of CMOS devices can benefit greatly from integration of on chip light sources, mixed-signal and analog CMOS. In this paper we discuss recent results in the application of disc lasers for analog signal transmission such as radio over fiber. Large analog modulation bandwidth is demonstrated, and transmission of 64 and 256 QAM signals on a 5GHz RF carrier is successfully demonstrated with low EVM performance penalt
