Latest Patents
Shigeru Kanazawa holds a patent for an optical transmitter designed to significantly suppress fluctuations in frequency response characteristics caused by fabrication errors in internal wire length. This invention also aims to reduce the subcarrier size of the optical transmitter module. The optical transmitter features a subcarrier that supports an RF wiring board, a modulated laser chip, and a terminating resistor. A ground pad is located on the upper surface of the subcarrier, and a wire electrically connects the RF wiring board and the modulated laser chip. The arrangement of these components is optimized in the width direction of the subcarrier. The length of the wire in the electric path, which starts at the RF wiring board, passes through the terminating resistor, and reaches the ground pad, is specified to be between 0.5 to 1.5 mm or has an inductance of 0.4 to 1.2 nH. This innovation is a testament to his expertise and dedication to advancing optical technology.
