Latest Patents

Among her latest patents is the **Electro-opto-mechanical Micro Gyroscope**. This device utilizes a substrate that defines a vacuum cavity containing a birefringent microrotor. A light source effectively directs light through the substrate, establishing an optical spring effect that influences the microrotor's initial reference position and its rotational and translational movements. Importantly, a receiver can detect light changes passing through the cavity, which are indicative of microrotor position variations, proving valuable for inertial navigation systems.

Another cutting-edge patent is the **Optical Waveguide**, which encompasses a silicon wafer and an intricately patterned silicon substrate designed into a silicon waveguide. The manufacturing process involves depositing a cladding on the wafer using plasma-enhanced chemical vapor deposition (PECVD). This method not only ensures a lower density and refractive index in cladding portions but also enhances the light confinement within the waveguide, effectively reducing transmission losses.
