Title: Innovations of Zhuli He in All-Optical Boolean Logic Devices

Introduction

Zhuli He is a prominent inventor based in Hubei, China. He has made significant contributions to the field of optical logic devices, particularly in the development of phase-change all-optical Boolean logic devices. His work has led to the filing of two patents that showcase innovative methods for implementing logic operations using light.

Latest Patents

Zhuli He's latest patents include the "Y-branch type phase-change all-optical Boolean logic device" and the "all-binary logic implementation method therefor." The Y-branch type device features a waveguide with a Y-branch structure and phase change function units. This device utilizes a high-power light pulse to write data into the phase change function unit, allowing for a phase change that alters optical properties. The state of the unit can then be read using a low-power light pulse without changing its state. This method enables the implementation of all 16 binary Boolean logic calculations through a simple structure.

The second patent, which focuses on an all-photonic Boolean logic device based on a straight waveguide, includes a ridge-shaped structure and two phase change functional units. The device employs a Bragg grating to manage the write and read optical pulses, ensuring that the write pulses only affect the nearest phase change unit. This innovative design allows for the implementation of 16 full Boolean logic functions through a three-step write operation.
