Title: Tomoyuki Izuhara: Innovator in Optical Technologies

Introduction

Tomoyuki Izuhara is a prominent inventor based in Pleasanton, CA, known for his significant contributions to optical technologies. With a total of seven patents to his name, Izuhara has made remarkable advancements in the field of optical beam scanning and photodetector technologies.

Latest Patents

One of his latest patents is the "Integrated thin optical beam scanner." This innovative optical beam scanning semiconductor device features a 1×N electrically controlled, integrated optical switch matrix. It is specifically designed with integrated optical grating output couplers at each of the N output waveguides of the 1×N switch. By selecting one of the N outputs, the device allows an optical output beam to scan in free space. The variation in the grating output coupler design enables a smart scanning device with multiple controllable beam characteristics.

Another notable patent is the "Semiconductor photodetector array sensor integrated with optical-waveguide-based devices." In this invention, an optical signal enters single photon avalanche diode cells (SPAD) in a SPAD array, triggering photo event currents. The optical waveguides in the sensor carry an internal optical signal, while a 1xN splitter divides the optical power into waveguide branches. The coupling structure, which comprises N-positive-intrinsic-negative diode photodetector/waveguide structures, converts photo event currents from SPAD cells into a change in the internal optical signal. A waveguide combiner integrates the modified internal optical signals, and a photodetector ultimately detects the internal optical signal, outputting an electrical signal.
