Title: Innovations of Marcel W Pruessner
Introduction
Marcel W Pruessner is a notable inventor based in Silver Spring, MD (US). He has made significant contributions to the field of photonic integrated circuits, holding a total of 12 patents. His work focuses on advanced optical technologies that enhance the functionality and efficiency of optical systems.
Latest Patents
One of his latest patents is the "Micromechanically-tunable polarization rotator for photonic integrated circuits." This apparatus includes a polarization rotator and a polarization splitter, each featuring a first optical waveguide. The polarization rotator incorporates a movable symmetry-breaking micro-electro-mechanical systems (MEMS) dielectric perturber, which is separated from the first optical waveguide by a gap. This design allows for precise control of polarization rotation within the optical waveguide. Additionally, the polarization splitter is designed to control polarization splitting between the optical waveguides through a MEMS actuator.
Another significant patent is related to "Methods and apparatuses for optical mode conversion." This invention includes a substrate with a first and second waveguide, along with a MEMS perturber and a controller. The first waveguide is structured with an input section, a bend section, and an output section. The controller manages the movement of the perturber, which alters the effective refractive index of the first waveguide, thereby facilitating mode conversion.
