| 英文摘要 | PURPOSE:To change an effective refraction factor and internal loss and to enable change of oscillation wavelength and oscillation position by forming a plurality of gain waveguide paths close to each other and by changing a current to supply to each electrode. CONSTITUTION:An example of distribution feedback gain waveguide laser having three stripe electrodes is taken. Currents supplied to the three electrodes 1 are named I1, I2, and I3, respectively. Since these upper electrodes 1 are formed close to each other and the waveguide path is a gain waveguide type, a current I2 is injected to a middle electrode 1 at first for laser oscillation. An effective waveguide path width can be changed by injecting a current to electrodes I1 and I3 on the right and the left of the middle electrode I. Therefore, oscillation wavelength can be changed by thus changing an effective refraction factor and an oscillator loss. A light emission position can be made under the electrode I2 by letting I1=I3 and can be deflected right and left from the center by changing the size of I1 and I3. |
