With a remarkable portfolio of 19 patents, he has dedicated his career to advancing innovations that enhance the functionality and efficiency of optical systems.

Latest Patents

Tamamura's latest patents include a microactuator device and an optical switching system. The microactuator device features a movable plate fastened to a substrate through flexure parts, allowing it to move upward and downward relative to the substrate, which acts as a fixed electrode. This design utilizes electrostatic force generated between the electrode parts and the substrate as well as a current path in a magnetic field that produces a Lorentz force when activated. This mechanism permits the movement of a mirror in the optical path, ensuring precise control of light signals.

In his optical device patent, Tamamura devised a system where an insertion plate is held by a flat cantilever. The flat magnet is aligned such that it interacts with the current flowing through the cantilever's wiring. The resulting Lorentz force enables the cantilever to displace the insertion plate, allowing it to be inserted or removed from the optical waveguide slit. This innovation effectively switches the optical path of signal light or adjusts the optical beam's intensity.
