**Title: Innovations by Inventor John D. Jackson**
Introduction
John D. Jackson, an accomplished inventor based in Harlow, Great Britain, has made significant contributions to the field of optics. His innovative spirit and technical expertise are exemplified by his patent, which addresses key challenges in semiconductor laser technology.
Latest Patents
One of his notable inventions is the acousto-optic isolator designed for semiconductor laser diodes. This patented device utilizes a Fabry-Perot resonator, which is finely tuned to the optical frequency of the laser (f.sub.o). The isolator features an acousto-optic Bragg diffraction device that makes use of surface acoustic waves launched from a transducer at frequency (f.sub.a). The light focused by a lens to the load has a resultant frequency of f.sub.o + f.sub.a. Reflected light experiences a frequency change to f.sub.o + 2f.sub.a within the diffraction device, effectively being blocked by the resonator. The undiffracted light is detectable by a photo-detector, which facilitates a feedback control loop to stabilize the light source to the resonator.
