Marcus Duelk is an accomplished inventor based in Atlantic Highlands, NJ (US). He has made significant contributions to the field of communication technology, holding a total of 3 patents. His work primarily focuses on methods of signal transmission and optical multiplexing.

Latest Patents

One of his latest patents is a method of signal transmission in a WDM communication system. In this invention, a transmitter is equipped with a Mach-Zehnder modulator (MZM) that produces an optical signal corresponding to a duobinary data stream. The MZM modulates a beam of light, applying a three-level electrical signal to control light transmission. This innovative approach allows for a relative phase shift between optical bits that differs from the conventional 180 degrees, thereby reducing decoding errors at the receiver.

Another notable patent is for an optical time division multiplexer. This TDM comprises at least two wavelength-tunable devices that output signals, each capable of changing signal wavelength in response to a change signal. The design includes a series of on-off gates that control the passage of signals based on the operational status of the wavelength-tunable devices. This invention enhances the efficiency of signal transmission in communication systems.
