Title: The Innovations of Loren F. Stokes
Introduction
Loren F. Stokes is a notable inventor based in Palo Alto, CA. He has made significant contributions to the field of fiber optics, holding a total of 3 patents. His work focuses on advanced sensor technologies that have applications in various industries.
Latest Patents
One of his latest inventions is the Stabilized Fiber Optic Sensor. This innovative sensor comprises a length of optical fiber that forms a loop, along with a fiber optic directional coupler for optically closing the loop. The combination creates a resonant cavity for light circulating through it. A PZT cylinder, around which the fiber loop is wrapped, is utilized to control the total round trip phase delay of the circulating light, thereby controlling the intensity of the optical output signal. The phase delay is adjusted to maximize sensitivity to changes in phase. When the fiber loop is exposed to acoustic waves, the loop length changes, causing variations in the optical output signal. By detecting these variations, the frequency and intensity of the acoustic waves can be determined. Additionally, the sensor includes a feedback system to stabilize the fiber loop against low-frequency thermal drift.
Another significant patent is the Brillouin Ring Laser. This device comprises a fiber optic resonator formed from a loop of fiber optic material and a fiber optic directional coupler for optically closing the loop. This invention further exemplifies Stokes' expertise in fiber optic technologies.
