Title: Keisuke Mise: Innovator in Micro Optical Technology
Introduction
Keisuke Mise is a prominent inventor based in Saitama, Japan. He is known for his contributions to the field of optical technology, particularly in the development of micro optical heads for data reading and writing.
Latest Patents
Mise holds a patent for a micro optical head with an optically switched laser diode. This innovative device is designed for optically reading and/or writing digital data on a recording medium. The technology utilizes a self-coupled semiconductor laser positioned close to the recording medium. The laser's bias current is carefully calibrated to be less than a first threshold current, which corresponds to a low reflection factor, and greater than a second threshold current, which corresponds to a high reflection factor. The output light from the laser can either be strong stimulated emission light, indicating a high reflection factor, or weak spontaneous emission light, indicating a low reflection factor. The micro optical head is mounted on a flying slider with a spacing length of less than several micrometers, producing a small beam spot of about 1 micrometer and achieving an excellent signal-to-noise ratio. Additionally, a photodetector for sensing the laser's output may be integrated on the same semiconductor substrate as the laser.
