Title: Keisuke Asami: Innovator in Wavelength Tunable Light Sources
Introduction
Keisuke Asami is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, particularly in the development of wavelength tunable light sources. With a total of 10 patents to his name, Asami continues to push the boundaries of innovation in his field.
Latest Patents
Asami's latest patents include a wavelength tunable light source and a light source for an external cavity laser. The wavelength tunable light source features a semiconductor laser with an anti-reflection film on one end surface. A lens collimates the light beam emitted from this surface, while a combination of a diffraction grating and a mirror selects the desired wavelength. This design allows for effective laser oscillation by returning the selected light to the semiconductor laser. The light source for an external cavity laser comprises a semiconductor laser with specific coatings on its facets, lenses, a diffraction grating, and a mirror. This configuration enables the emitted light to be converted into parallel light, which is then processed to select and output the desired wavelength.
