He has made significant contributions to the field of substrate manufacturing, particularly in the development of methods for creating periodically poled regions. With a total of 2 patents to his name, Tokuda's work has advanced the technology used in various applications.

Latest Patents

Tokuda's latest patents include a "Method of manufacturing substrate having periodically poled regions." This innovative method involves observing a current while applying a gradually increasing voltage between electrodes on the front and rear surfaces of a substrate. Periodically poled regions are formed by applying a DC voltage, which is either the voltage value at that time or another value obtained by adding a predetermined value to it. This process is executed for a predetermined time when an inverted current is observed.

Another notable patent is the "Method of fabricating board having periodically poled region." In this method, a polarization inverting region is created using a board made from a single crystal of lithium tantalate. A direct current electric field, with an intensity equal to or lower than 5 [kV/mm], is applied for at least 1 second. This approach allows for the formation of a periodically poled region without the need for complex configurations for applying pulse voltages or strong electric fields.
