摘要：

Semiconductor ring lasers have been designed and integrated with auxiliary coupled optical circuits to beat together the contra-rotating modes. The Sagnac effect predicts a beat frequency proportional to rotation rate, although no beat frequency has yet been observed. Calculations from theory predict a high lock-in frequency; improvements to the design and fabrication of the devices should reduce the lock-in frequency to a useful level.
