Latest Patents

Fred S. Hirt holds a patent for a "Method and apparatus for suppressing relative intensity noise (RIN) and improving transmission signals." This invention involves a method and apparatus within an optical transmitter designed to suppress RIN by generating at least two optical signals with differing wavelengths. These signals are combined into a composite output signal, which has an output power value equal to the sum of the power values of the individual optical signals. The composite output signal is then transmitted over a communication medium, ensuring that the information content of the optical signals remains substantially equivalent. This innovative approach provides a reduction in RIN compared to a single optical signal transmitted over the same medium.
