Thank you for visiting my web-site. Based on the development of high-performance DFB lasers for optical fiber communication, for 40 years, I have been pursuing the high functionality of optical semiconductor devices. I am making efforts to realize ultra-high-speed electronic devices by utilizing the crystal growth technology I have cultivated there. I would be happy if you could convey a part of that feeling.
