Title: The Innovations of Marvin Chodorow
Introduction
Marvin Chodorow, a distinguished inventor based in Stanford, California, holds an impressive portfolio of nine patents. His pioneering work in fiber optics has significantly advanced the field, leading to enhanced technologies that are critical in modern communication systems.
Latest Patents
Among Chodorow's notable inventions is the Fiber Optic Amplifier. This innovative device features a pair of small diameter optical fibers arranged side by side, where the first fiber serves as a pumping source, and the second fiber is doped with a lasing material that operates at the signal frequency. The design facilitates the amplification of signals by enabling the second fiber to stimulate the emission of coherent light, achieving low losses while providing efficient transfer of pumping light.
Another recent patent is the Stabilized Fiber Optic Sensor. This sensor comprises an optical fiber that forms a loop, coupled with a fiber optic directional coupler. This setup creates a resonant cavity for circulating light. A PZT cylinder, around which the fiber loop is wrapped, controls the total round trip phase delay of the light, thereby adjusting the optical output signal's sensitivity to variations, such as those caused by acoustic waves. This invention not only measures phase changes effectively, but it also incorporates a feedback system to stabilize the fiber loop against low-frequency thermal drift.
