Title: Innovations of Steven R. Sakamoto
Introduction
Steven R. Sakamoto is a notable inventor based in Santa Clara, CA. He has made significant contributions to the field of optical technology, holding 2 patents that showcase his innovative approach to optical memory and logic systems.
Latest Patents
One of his latest patents is titled "Optical memory and logic using cross-switches." This invention describes an all-optical, asynchronous binary storage cell that utilizes optically induced total internal reflection cross-junction waveguide switches. The term 'all-optical' indicates that optical data signals are directed through optical control signal inputs without needing conversion between optical and electrical domains. This binary cell serves as a fundamental component for a programmable all-optical random access memory (AORAM) device, which is essential for circuits and networks requiring optical buffers.
Another significant patent by Sakamoto is "Optically induced total internal reflection X-junction waveguide optical switch, network and optical switching method." This invention provides optical high data rate switching at a wavelength or packet level using optical tone addressing. The optical signal routing is achieved through optically induced total internal reflection at the intersection of an X-junction waveguide structure. The total internal reflection effect is manipulated by a high-intensity optical pump beam, which is separate from the optical data signal. This technology may lead to the formation of optical switching networks using cascaded pluralities of optical waveguide switches.
