| 英文摘要 | A ring laser gyro includes a tapered portion in a part of an optical waveguide, a plurality of ring resonator semiconductor lasers optically independent of each other on a common plane, and a plurality of electric terminals for detecting a change in the impedances of said ring resonator semiconductor lasers. The tapered portion includes a first portion where a width of the optical waveguide is gradually widened along a direction of propagating a laser beam clockwise and a second portion where the width of the optical waveguide is gradually narrowed along the direction, and further comprising a first ring resonator semiconductor layer in which said first portion is longer than the second portion, and a second ring resonator semiconductor layer in which said second portion is longer than the first portion. |
