Introduction

Atsushi Kanno is a prominent inventor based in Koganei, Japan. He has made significant contributions to the field of optical communication technology, holding a total of seven patents. His work focuses on enhancing the efficiency and capabilities of photodetectors and optical receivers.

Latest Patents

One of Kanno's latest patents is a high-speed photodetector array. This invention aims to provide a photodetector that enables the reception of massively parallel optical communication. It allows for the instantaneous reception of large volumes of data for multi-mode or multi-core transmission. The photodetector comprises a two-dimensional array of photodetectors, each with a light reception area measuring no more than 100 micrometers. The design includes a wire with a width of not more than 4 micrometers between the photodetectors, which are spaced apart by at least 20 micrometers.

Another notable patent is a common mode rejection ratio (CMRR) measurement device for coherent optical receivers. This invention provides a method and device capable of easily measuring the CMRR versus frequency characteristics of an optical receiver. The measurement process involves splitting light into two different paths and obtaining first and second optical two-tone signals. These signals are then input into a coherent receiver for measurement, allowing for the determination of the CMRR on both the signal light and local light sides.
