This breakthrough represents a fundamental shift in inertial sensing architecture, replacing traditional electrostatic actuation with a purely optical approach.

In this novel design, the HRG’s resonator flexural mode is both excited and measured using light alone. By eliminating conventional electrode-based capacitive excitation and readout, the system removes the need for electrostatic actuation electrodes entirely.

"This is a significant step forward for inertial sensing," said Prof. Nir Sharon, Chief Quantum Technology Officer at Quantum X Labs. "By moving to an all-optical drive and readout, we simplify the resonator structure while opening the door to a new class of electrically isolated, high-performance sensors."

Traditional HRGs rely on electrodes to induce and measure motion within the resonator. These components add complexity, introduce potential sources of noise and drift, and impose design constraints. Quantum X Labs’ optical approach addresses these challenges by:

Eliminating electrode structures from the resonator assembly
Reducing system complexity and potential failure points
Enabling intrinsic electrical isolation
Creating a pathway toward next-generation photonic inertial systems
The demonstration validates the feasibility of fully optical excitation and sensing in precision gyroscopes—an advancement that could have far-reaching implications for navigation systems in aerospace, defense, and autonomous platforms, particularly in environments where electromagnetic interference or electrical isolation is critical.

Quantum X Labs plans to continue refining the technology, with future work focused on potential joint ventures and cooperation for performance optimization, system integration, and scaling toward deployable inertial measurement units (IMUs) in aerospace, defense and other commercial applications.
