Latest Patents

Mizukami's latest patents include an optical switch, an optical switch control method, and a communication system. The optical switch control method involves detecting light intensity upon a perturbation and utilizing an error calculation/correction unit in a control unit. This unit corrects and updates initial manipulated variables based on perturbation manipulated variables to maximize light intensity. The method assumes that the time series data of the acquired output light intensity can be approximated to a cosine function. The error calculation/correction unit calculates a phase difference between the cosine function and a sine or cosine function used to set x- and y-axis perturbation patterns for a circular trajectory perturbation. This innovative approach allows for precise adjustments to the tilt angle of a mirror, enhancing the overall performance of optical systems.

Another significant invention is the mirror control device, which includes a pivotally supported mirror and electrodes spaced apart from the mirror. This device generates a driving voltage corresponding to the desired tilt angle of the mirror for each electrode. It also includes a bias voltage generation means that ensures the tilt angle of the mirror maintains a predetermined value when independently applied to each electrode. This technology is crucial for improving the accuracy and efficiency of optical devices.
