Title: The Innovative Contributions of Paul P Webb
Introduction
Paul P Webb is a notable inventor based in Beaconsfield, CA, recognized for his significant contributions to the field of photodetectors. With a total of 16 patents to his name, Webb has made remarkable advancements in the technology of avalanche photodiodes, which are crucial for various applications in optics and electronics.
Latest Patents
Webb's latest patents include groundbreaking inventions such as low-noise, reach-through avalanche photodiodes. This new reach-through APD structure features a five-layer, double-drift-region, double-junction device, characterized by a p.sup.+ -p-n-p.sup.- -n.sup.+ structure. The innovative design ensures that the middle three layers of the APD are fully depleted when the device is biased to its normal operating voltage. This configuration allows only primary carriers generated in the first drift region to experience full avalanche gain, resulting in significantly lower dark current and noise levels compared to conventional reach-through APDs. Furthermore, this new structure facilitates the fabrication of integrated arrays of APDs, which are more durable and easier to produce than previous designs. Another notable invention is the avalanche photodiode with a central zone in active and absorptive layers. This photodetector features a charge-multiplication region that is spatially separated from the detector surface, enhancing its performance without the need for a hard-to-grow quaternary layer.
