Latest Patents
Franck's latest patents focus on duo-binary signal encoding. One of his inventions is an apparatus designed to implement duo-binary signal encoding in high-power, high-speed transmission systems. This technology aims to mitigate the problem of stimulated Brillouin scattering. A dual-drive Mach-Zehnder interferometer modulator is utilized, with data applied to both modulation inputs. The voltage difference between the two modulation inputs ranges from -V.sub..pi. to +V.sub..pi.. In one embodiment, the data signal is applied to one input, while the same signal, delayed by one bit, is applied to the second input. The modulator is biased to achieve minimum throughput when both inputs are identical. In another embodiment, the data signal is applied to one input, and the complementary data-bar signal, delayed by one bit, is applied to the second input. This innovative implementation has been experimentally verified, showing a power penalty of less than 1 dB compared to conventional binary signals. It is also demonstrated that significant increases in stimulated Brillouin scattering will enhance the bit rate of duo-binary encoded signals.
