Latest Patents

Among his latest patents are two groundbreaking inventions: the Optical Transmission System and the Optical Transmission System Using In-Line Amplifiers. The first patent outlines an optical transmission system featuring a dispersion compensator situated within the receiver. This system utilizes an electro-optical signal converter and a post-amplifier to optimize the performance of RZ-coded optical signals. By implementing a positive red-chirp parameter, the system effectively cancels non-linear effects and reduces inter-symbol interference, ultimately minimizing total dispersion and increasing optical output power.

The second patent introduces a method for connecting transmitters and receivers through transmission paths and repeaters while incorporating in-line amplifiers. This invention employs a consistent dispersion compensator in the transmitter and a dynamic compensator in the receiver to address dispersion across preceding transmission paths. The innovative approach utilizes red chirping on the transmitting side, which efficiently compensates for pulse width spread during transmission.
