Abstract
A solid state fiber optical semiconductor ring laser gyro apparatus with nonoptical readout which contains an optical fiber optically coupled with a optical amplifier diode which has a ground electrode and a plurality of non ground electrodes, which are both electrically and spacially separated and disposed across the optically active channel of the optical amplifier diode, the magnitude and direction of rotation of the optical fiber ring can be determined by examining the differences in phase information between the outputs on the plurality of non ground electrodes.
