Title: Nobuhiro Sakakibara: Innovator in Optical Technology
Introduction
Nobuhiro Sakakibara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, holding a total of 2 patents. His work focuses on enhancing the functionality and efficiency of optical systems.
Latest Patents
Sakakibara's latest patents include an optical polarization controller and a method for measuring light from an optical fiber. The optical polarization controller comprises a polarization control element, a polarizer, a light divider, and a photo-detector. The polarization control element rotates the plane of polarization of an input signal light by a predetermined angle and outputs the result as a rotated signal light. The polarizer extracts a component of the rotated signal light with a specific plane of polarization, outputting it as a polarized signal light. The light divider then divides this polarized signal light into multiple polarized signal lights that maintain the same planes of polarization. The photo-detector detects the level of one of these polarized signal lights and supplies a control signal to the polarization control element, allowing for precise control of the output signal light's polarization.
The second patent involves a method for measuring light from an optical fiber, where the optical fiber is bent in a semi-spherical shape. A light dispersing member is attached to the bent portion, enabling measurement of the light emitted from this area through the dispersing member.
