Optical Signal Processing

While electronic digital signal processing (DSP) will be an important component of next-generation fiber-optic transmission systems, electronic DSP speeds ultimately limit the achievable per-wavelength optical transmission rates. At NEC OND, we are currently investigating and developing advanced all-optical signal modulation, processing and monitoring techniques that provide superior performance at ultra-high speeds (~1 Tb/s/lambda). Among our exciting research thrusts in this area are All-Optical Orthogonal Frequency Division Multiplexed (AO-OFDM) transmission, as well as all-optical sampling, signal generation and monitoring techniques.
