Abstract

In this work, we present an alternative approach to angular velocity optical sensing based on two-ring resonators. This configuration admits the use of a standard laser diode source ( 0.1 nm , 10,000 MHz, FWHM) reaching higher sensitivities when narrow spectral laser sources ( 1 MHz , FWHM) are used. We compare this configuration with the standard single-ring resonator angular rate sensor (SRARS), which must use a narrow laser at input. Finally, we conclude that the sensitivity of this new approach can also be enhanced by coupling high-power broadband laser sources in a large range (from 1 ° / h to 10,000 ° / h ), reaching performance similar to that of a standard SRARS configuration.
