Title: Innovations by Jean-Francois Seurin in Optical Sensing Technology
Introduction
Jean-Francois Seurin, an accomplished inventor based in Princeton Junction, NJ, has made significant contributions to the field of optical sensing technology. With a remarkable portfolio of 13 patents, he has been a pioneering force in the development of innovative sensing methods and laser technologies.
Latest Patents
Among his latest patents, Jean-Francois is known for his inventions related to sensing methods and sensor systems. One notable patent describes a sensing method that utilizes a vertical cavity surface emitting laser (VCSEL) to oscillate and emit a laser beam. This method employs self-mixing interferometry, where a diaphragm reflects a portion of the laser beam back into the VCSEL for movement sensing, enabling the detection of external properties without the need for a photo-detector.
Another significant patent focuses on low divergence vertical cavity surface emitting lasers. This invention involves VCSELs that produce exceptionally narrow divergent light beams by incorporating an additional epitaxial layer. This enhancement increases the cavity length of the VCSEL, leading to higher power output in fewer larger diameter transverse modes, which notably reduces the output beam divergence.
Career Highlights
Throughout his career, Jean-Francois has worked at several reputable organizations, including Princeton Optronics, Inc. and Ams Sensors Asia Pte. Ltd. His contributions in these roles have propelled advancements in laser technology and optical sensing applications.
Collaborations
Jean-Francois has collaborated with talented professionals in the field, notably Chuni Lal Ghosh and Laurence Watkins. These collaborations have further enriched his work and driven innovation across various projects.
