Title: Richard A. Linke and His Rewritable-Wavelength Semiconductor Laser
Introduction
Richard A. Linke is an inventor associated with Lawrenceville, New Jersey, and NEC Corporation. His work includes a patent for a semiconductor laser whose operating wavelength can be changed by rewriting a grating in photorefractive material.
Latest Patents
Linke is credited with 1 patent: “Semiconductor Laser with a Rewritable Wavelength Stabilizer.” The invention uses a grating written into photorefractive material as a laser mirror, with the grating’s period determining the laser diode’s oscillation wavelength. By changing the material’s temperature and illuminating it under specified conditions, the grating can be erased and rewritten, allowing the laser’s wavelength to be changed repeatedly. Operating the diode at low temperature helps preserve the grating.
Career Highlights
Linke’s documented patent work connects him with NEC Corporation and focuses on semiconductor laser wavelength control. The patent describes a method for adjusting a laser’s wavelength through a rewritable optical grating.
Collaborations
Hirohito Yamada is identified as Linke’s coworker. The available information does not specify his role in the patent or the invention.
Conclusion
Richard A. Linke’s patent presents a rewritable-grating approach to changing and stabilizing a semiconductor laser’s wavelength.
