Integrated optical gyroscope with inverse weak value amplification

Abstract

We apply inverse weak value amplification to an integrated Sagnac interferometer gyroscope. We demonstrate rotation measurement with the weak value gyroscope.

Research progress of integrated optical gyroscope

“…This scheme enhances the sensitivity of the gyroscope by at least four orders of magnitude in a low Q micro-resonator. In addition to doping and dispersion control, some researchers have also utilized nonlinear effects [50] and weak value amplification [51] to enhance the performance of optical microcavities and achieve high-performance IROGs.…”

“…In 2018, researchers from the California Institute of Technology [42] utilized the reciprocity of a passive optical network to increase the gyroscope signal-to-noise ratio, resulting in the development of the world's smallest gyroscope on a 2 mm 2 silicon chip with a random walk angle of 650 deg/ p h. Notable research groups working on Brillouin scattering include Zhang's and Silver's team at Caltech [49,50] , the University of California, Santa Barbara, and Honeywell [51] . Li's team proposed the SiO 2 micro-ring-based Brillouin gyroscopes in 2017 [52] and in Fig.…”
