Career details 3/5 1984 – 2000｜Santec (Board Director & CTO, IPO)
A string of world-first optical products, at the front line of optical communications
Every product developed from scratch—handling optical design, electronic circuit design, and overall project leadership as CTO, and guiding the company to IPO as board director & CTO. The tunable lasers he developed were delivered to research institutes worldwide, including AT&T Bell Labs and BT Labs, holding the top market share at the time.
Key products and achievements
- Developed the world's first optical-fiber transmitted-light distribution measurement system for optical communications, including its IR image-processing system — 1984
- Developed systems based on ultra-high-precision optical path-length measurement using white-light interferometry (semiconductor wafer trench-depth measurement, high-precision film-thickness inspection, optical-fiber chromatic-dispersion measurement)
- World-first commercialization of tunable laser sources and frequency-stabilized light sources (stability below 0.1 ppm) for optical communications
- Developed 1.3μm- and 1.55μm-band tunable lasers, sold to research institutes worldwide—including AT&T Bell Labs and BT Labs—with the top share at the time
- Developed a state-of-the-art LF image-processing system for DRAM (3,000 ICs on board), which became the industry standard — 1990
- Obtained Intel equipment certification for the world-standard MPU package inspection; cumulative sales exceeding ¥5 billion — 1997
- Top domestic share in BGA inspection systems — 1998; provided inspection guidance to Ibiden and Shinko Electric Industries
Expertise accumulated in this era
- IR vidicon image-correction technology, real-time image enhancement, high-precision image processing
- Development of large-scale hardware image-processing systems — 20+ years
- External-cavity tunable laser design, control technology, and frequency stabilization
- High-precision analog circuit design — high-sensitivity sensing, high current, high voltage, fast pulses, and more
