Latest Patents

Ajoy Ghatak holds a patent for a "Small residual dispersion fiber connected with a dispersion compensating fiber." This invention involves an optical fiber link that features a small residual dispersion fiber (SRDF) connected to a dispersion compensating fiber (DCF). The SRDF has a positive dispersion slope, while the DCF has a negative dispersion slope. The dispersion slope of the DCF is specifically matched to that of the SRDF, allowing the DCF to effectively compensate for the accumulated dispersion in the SRDF within the wavelength range of approximately 1530 nm to 1565 nm, which corresponds to the C-band of erbium doped fiber amplifiers (EDFA). This innovation is crucial for enhancing the performance of optical communication systems.
