| 摘要 |
The present invention provides an optical gyro adapted to reduce the coupling loss generated when emitted laser beams are incident upon a photo detector and the noise generated by the laser beams reentering the laser from an external point of reflection as well as to a method of operating such an optical gyro. A gyro according to the invention comprises a ring resonator type semiconductor laser for having laser beams transmitted circularly in opposite directions relative to each other and a terminal for detecting a beat signal, the active layer of the semiconductor laser being ring-shaped. <IMAGE> |
