A novel method of measurement of lasing characteristics for a ring laser diode is proposed without branching of the optical lasing power. The lasing power and the linewidth as a function of the injection current have been measured by detecting the RF power by the terminal voltage change of a ring LD. The linewidth is estimated to be 55 kHz atl=1.75lth.
