Title: The Innovations of Robert Lewén
Introduction
Robert Lewén is a notable inventor based in Tyresö, Sweden. He has made significant contributions to the field of optical communication, holding a total of 9 patents. His work focuses on developing advanced optical devices that enhance communication technologies.
Latest Patents
One of Lewén's latest patents is an optical communication device. This device includes a driver component that achieves a driving voltage and a modulator component that can receive light from a laser. The modulator is designed to produce a modulated light signal based on the driving voltage. Additionally, the device features a transmission line that transfers the driving voltage between the driver and modulator components. Notably, this transmission line is not impedance matched to the driver component, having an impedance at least 20% lower than the output impedance of the driver, while being impedance matched with respect to signal reflections to the modulator component.
Another significant patent is for an optical interference modulator. This device comprises a main input and output, along with an optical splitter connected to the main input. It includes first and second MMI couplers, each with access ports connected to the splitter and the main output. A light reflector is arranged to reflect light from the primary and secondary waveguides back into the respective waveguide. This design allows for modulation of the phase of light traveling along the waveguides in either direction.
