| 英文摘要 | PURPOSE:To oscillate on a fixed axial mode by a method wherein control signals that cancel the fluctuation of oscillation wavelengths are impressed on an electrode controlling the refractive index of the optical waveguide. CONSTITUTION:Modulation signals generated in a modulation signal source 101 are branched at a branch circuit 102. The first mixing circuit 107 injects the signals into a semiconductor laser 109 after their mixing with DC currents supplied from a DC power source 105. The currents branched to the second mixing circuit 108 are injected into the laser 109 as the control signals after mixing with the currents supplied from a DC power source 106. When the modulation signals are impressed on an electrode 113, the refractive index varies in the active region located immediately under the electrode. The control signals impressed on an electrode 115 inhibit the fluctuation of axial mode occuring with the variation in refractive index. |
