Latest Patents
Vredenberg holds a patent for an optical device that features a Fabry-Perot cavity formed by two reflective mirrors. This device incorporates an active layer doped with a rare earth element from the lanthanide series, specifically elements numbered 57 through 71. The design ensures that the thickness of the active layer is a whole number multiple of .lambda./2, where .lambda. represents the operating wavelength. The fundamental mode of the cavity resonates with the emission wavelength of the selected rare earth element. His invention achieves cavity-quality factors exceeding Q=300 and finesses of 73, utilizing structures made of two Si/SiO.sub.2 distributed Bragg reflector mirrors and an Er-implanted (.lambda./2) SiO.sub.2 active region. The results demonstrate a significant enhancement in luminescence intensity along the optical axis compared to structures without a cavity.
