Claims
1. A spherical integrated-photonic gyroscope containing a source of a coherent optical signal, an interference path and a phase shift detector, characterized in that the interference path is made using a silicon photonic waveguide and includes an S-shaped antisymmetric inversion unit, a fractal cascade of microinterferometers and an integrated interference cell, wherein said elements are connected in series and placed on a common photonic chip, and the gyroscope is made with the possibility of forming a stable interference state sensitive to angular displacements.
2. A gyroscope according to claim 1, characterized in that the S-shaped antisymmetric inversion unit is made in the form of a photonic waveguide with mirror-inverse geometry, providing a phase reversal of the signal by 180°.
3. A gyroscope according to claim 1, characterized in that the fractal cascade of microinterferometers contains at least two levels of nested interference loops with scaling according to the principle of self-similarity.
4. A gyroscope according to claim 1, characterized in that the integral interference cell is made in the form of a multimode interferometer on a silicon photonics platform.
5. A gyroscope according to claim 1, characterized in that the coherent signal source, S-node, fractal cascade, interference cell and phase shift detector are located on a common photonic chip and are electrically and / or optically connected into a single navigation system.
