英文摘要	PURPOSE:To keep an oscillation mode constant, by connecting a specific inductance in series to a control current which is applied to a waveguide part with a common power source, thereby interposing a resistance between the power source and a control electrode. CONSTITUTION:An exciting current passes the first chip resistance 11 and a wire 4 and then, excites the active part of a laser element A current flowing in a waveguide passes an inductance 14 for cutting off high frequencies and a resistance 12 and further, is injected into the active part of the laser element 1 through a wire 5 to generate optical signals which are modulated by the signals to be transmitted. Then, electrodes 2 and 3 are mounted at both active and waveguide parts of a single mode laser possessing the active and waveguide parts and this device permits a control current J to apply to the waveguide part. Although the control current J uses the same power source as that of the exciting current I, the inductance and resistance of 2nH or more are interposed between the above power source and control electrodes. Light-emitting wavelengths thus become stable and no mode jump takes place according to electric currents.
