Latest Patents

Tsadka's latest patents include a "Method and apparatus for demodulating and regenerating phase modulated optical signals". This invention features a Differential Phase Shift Keying (DPSK) / Differential Quadrature Phase Shift Keying (DQPSK) receiver that utilizes an optical splitter. The splitter separates the received optical signal based on an optical power splitting ratio into multiple received optical signals. Additionally, it incorporates multiple optical filters that allow for the processing of various filtered received optical signals, generating corresponding electrical detection signals, which are then amplified to produce a combined reception signal.

The second patent, "All-optical, tunable regenerator, reshaper and wavelength converter", consists of a system designed for regenerating and converting optical signals. This innovative solution provides both 2R (reamplification and reshaping) and 3R (reamplification, reshaping, and resynchronization) regeneration. The system employs a tunable continuous wave (CW) laser source, an optical circulator, a semiconductor optical amplifier (SOA), and a sharply cutoff spectral filter. This setup allows for the effective processing of CW signals in relation to input data bits, enhancing the overall signal quality.
