Title: Innovations of Alexander Sergienko
Introduction
Alexander Sergienko is a prominent inventor based in Boston, MA, known for his significant contributions to the field of optics and photonics. He holds a total of five patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on advanced imaging techniques and the generation of entangled photons.
Latest Patents
One of Sergienko's latest patents is the Correlation Confocal Microscope. This innovative device utilizes correlated photon pairs to enhance resolution. It features a light beam that converges on a sample, with an objective that collects light from this point to create an image beam. A modulator applies a spatial pattern of modulation to the source light beam, defining spatially correlated photons. These correlations are preserved in the modulated light gathered from the sample. A modulation-selective filter function is then applied to generate a filtered light beam of like-modulated photons. Additionally, a coincidence detector identifies temporally coincident photon pairs, producing a pulse output that indicates the light-detectable properties of the sample.
Another notable patent is for High-Flux Entangled Photon Generation via Parametric Processes in a Laser Cavity. This apparatus generates a robust source of doubly or multiply entangled photons. It includes a laser medium that produces classical laser light and a medium for second harmonic generation, which transforms this light to its second-harmonic frequency. The design incorporates an optical cavity element with highly reflective mirrors, facilitating the generation of entangled photons through parametric processes.
