A demo system at 105.1 Tbit/s over 14350 km was reported in the OFC'2016, and ultra high bit rate transmission and all optical switch have been the most keypoint of the optical fiber telecommunications and all optical networking. High speed optical signal processing, including all optical logic gates, wavelength convertor, all optical buffer, optical computations, etc., are employed at the switching node in the all optical network. In this article, some technologies about the high speed all optical digital signal processing for high speed optical fiber systems are presented with our related research works.
