a second fiber optic ring resonator comprising a second length of the fiber optic material wound around a second hub, wherein the first hub and second hub are constructed of the same material and the first optical beam and the second optical beam circulate within the second fiber optic ring resonator in opposite directions; a first servo loop coupled to the first fiber optic ring resonator and the second fiber optic ring resonator, wherein the first servo loop is configured to control the first laser light source as a function of a first portion of the first optical beam that has circulated through the first fiber optic ring resonator, and a second portion of the first optical beam that has circulated through the second fiber optic ring resonator; a second servo loop coupled to the first fiber optic ring resonator and the second fiber optic ring resonator, wherein the second servo loop is configured to control the second laser light source as a function of a first portion of the second optical beam that has circulated through the first fiber optic ring resonator, and a second portion of the second optical beam that has circulated through the second fiber optic ring resonator; and a rotation rate detection circuit configured to output a rotation rate measurement as a function of a difference between a first resonant frequency of the second fiber optic ring resonator locked-on to by the first optical beam, and a second resonant frequency of the second fiber optic ring resonator locked-on to by the second optical beam; wherein the first servo loop is configured to control the frequency of the first laser source using a first feedback signal produced by a first servo, where the first servo generates the first feedback signal as a function of error signals derived from the first portion of the first optical beam and the second portion of the first optical beam;
